M.2 SSD Notebook Upgrade Guide
More and more laptops are doing away with, or supplementing their 2.5-inch bays with M.2 slots for solid-state storage. Here’s our guide to upgrading the M.2 SSD in your notebook.
M.2 is a form factor for storage drives in computers – that’s all it is. An M.2 storage drive will work only in a computer with an expansion slot designed to accept an M.2 storage drive.
Before you can upgrade the M.2 drive in your notebook, you need to identify how physically large of an M.2 drive your notebook can accommodate. As of mid-2017, there are three common lengths of M.2 drives:
- 40mm (Type-2240)
- 60mm (Type-2260)
- 80mm (Type-2280)
The most popular length used in notebook computers is 80mm, which is commonly referred to as Type-2280.
How do you know what length drive your notebook supports? One way to go about it is to use a system scanner, such as the one on Crucial’s website. We used it on our Dell Latitude 7480, and it told us the notebook supported an M.2 Type-2280 drive. That’s about as easy as it gets.
You could also refer to the specifications sheet of your notebook, which should be available on the manufacturer’s website. Calling into their support line and asking is a viable alternative.
If your notebook already has an M.2 drive installed, you can look up the drive model, and then research that drive online. To find the model of storage drive in your computer, first open the Device Manager. Here’s how to do it in Windows 10:
A closer look at your SSD under Device ManagerOn your taskbar, type Device Manager. The first result should be it, so click on the result to open it.
- In the Device Manager, expand Disk drives. This will show you the storage drives connected to your computer. If more than one drive is listed, you’ll need to search online for both model numbers to identify the M.2 drive.
In the case of our Dell Latitude 7480, the drive is a Toshiba THNSNK256GVN8. Toshiba’s website indicated the drive is sold in an M.2 form factor as a Type-2280 drive only. Since that drive is already installed in our Dell Latitude 7480, we know the notebook can accept a Type-2280 drive.
SATA or PCI Express?
Remember, M.2 refers to the form factor only; it has nothing to do with the interface the drive uses to connect with the computer. There are two common interfaces for M.2 drives as of this writing. The first is Serial ATA, or SATA. The second is PCI Express. You’ll want to take care to buy an M.2 drive that has the same interface as the drive you’re replacing, as a SATA drive will generally not work in a PCI Express slot, and vice versa. You can use a system scanner, like the one we mentioned in the last section, to identify the interface your notebook supports.
We have one final piece of advice if your notebook uses PCI Express drives. Pay very careful attention to whether your notebook supports PCI Express drives with the NVMe protocol built into them. The notebook itself must support the NVMe protocol in order for an NVMe drive to work. NVMe is a new technology designed to improve storage performance, but it’s not yet common.
There are a myriad of M.2 drives available on the market. Here’s our guidelines for selecting a drive:
- The drive should come from a reputable manufacturer, such as Crucial, Kingston, Corsair, Samsung, Intel, and others. Take a look at our SSD Forum to see what our users recommend.
- The drive should come with a three-year limited warranty at the minimum.
- Break this down to cost per gigabyte. Take the capacity of the drive, e.g. 512GB, and divide it by the cost. That will give you an idea of how expensive a given drive is in relation to others.
- Performance. For general use, this is one area where you probably won’t have to spend a lot of time researching, as just about all new M.2 storage drives on the market will not show noticeable performance differences for day-to-day usage. Pricier drives, such as PCI Express drives supporting the NVMe protocol, will generally have better performance for more storage-intensive activities, but the situations where a drive like that would really be worth the extra over a traditional drive are few and far between.
Online stores, such as Newegg, and manufacturers’ own website stores are ideal places to buy M.2 drives. Review the store’s return policy before pulling the trigger.
Now let’s get to the nuts and bolts of upgrading the M.2 drive in a notebook.
Tech level: Easy to Moderate
Required tools: Philips-head screwdriver, Microfiber towel, and an anti-static bag
Given the multitude of notebooks available on the market with M.2 storage drives, it’s impossible to develop a guide that will work for every notebook. The advice we prepared here is meant to be general, so you may have to modify or add steps to upgrade the M.2 drive in your particular notebook. Anything you do with this guide is at your own risk, and NotebookReview.com isn’t responsible for anything bad that happens. Remember to ask in our forums if you need help.
The notebook we’re using for presentation purposes is the Dell Latitude 7480.
The first step is to completely shut down the notebook computer. (If you’re planning to upgrade the drive that your computer’s operating system is installed on, you’ll want to have your operating system install media handy, and also have all your data backed up.) Unplug the notebook once it’s shut off. If your notebook has a removable battery, take take that out as well, and press the power button several times to drain any excess electricity. Finally, close the notebook’s display lid.
Your best bet before proceeding is to look up the service or owner’s manual for your particular notebook computer on the manufacturer’s website. Most of the time, access to a notebook’s internal components is done through the bottom of the chassis, and that’s the assumption we’re making in this guide.
Take the microfiber towel, and lay it on a clean working surface. Flip over your notebook, and place it display-side down on top of the towel. The purpose of using the towel is to prevent scratches to the notebook’s lid, or the surface the notebook is resting on.
Some notebooks have dedicated component access panels, which should be obvious. (Look for a cutout section.) Others, like our Dell Latitude 7480, require the removal of the entire bottom panel of the chassis. The removal of eight Philips-head screws is required on this notebook.
The screws on our Dell actually don’t come out; they’re held in by retainers when they are fully unscrewed.
The bottom panel can be gently pried up at this point. With our Dell Latitude 7480, we used our fingers to gently pry up the rear of the panel, next to the display hinge. After removal, put the panel and its screws in a safe place. If you feel like you’re forcing something, stop.
The next step is to identify the M.2 slot on the motherboard. The M.2 Type-2280 (80mm) drive in our notebook is about the size of a stick of chewing gum, highlighted at the lower right corner of this photo. An M.2 Type-2260 (60mm) drive would be three quarters as long as this drive, and an M.2 Type-2240 (40mm) drive would be half as long.
A single Philips-head screw holds the M.2 drive in place. Carefully remove this with a screwdriver, and put the screw in a safe place.
To remove the M.2 drive, use your thumb and forefinger to grasp each side of the drive about two-thirds of the way towards the screw point, and gently pull horizontally in the direction of the screw slot. It should slide out with minimal effort. If it feels like you’re using too much effort, you are.
Take the old M.2 drive and place it in an anti-static bag. You can probably use the bag your new M.2 drive arrived in. Be careful not to touch its gold connecting pins, as this can degrade the drive’s performance.
You’ll install your new M.2 drive by doing the reverse of what you just did. Line up the drive’s gold connection points with the slot on the notebook’s motherboard. The drive will only fit one way, and can’t be inserted upside down. Typically, the black chips on one side of the M.2 drive will face upwards if the drive is oriented correctly.
To verify you’ve pushed the drive in far enough, look at the screw cutout at the opposite end. You should see the screw hole on the notebook’s motherboard. Once this is the case, put back the Philips-head screw, and screw it back in. It shouldn’t be iron-tight, just enough that it won’t come loose. You can damage the M.2 drive and the computer if you tighten the screw too much.
And that’s it! Put back the bottom panel of the chassis, and screw it all back together. We suggest putting the bottom panel in place and gently pressing down the edges first, which will ensure it’s lined up correctly. Start with the screws on one side, and work your way around.
The points we outlined for selecting an M.2 drive for purchase are all you should need to make the right decision. Using the cost per gigabyte method for comparison will let you see which drives are a better value than others. As always, if a deal is too good to be true, it is.
The M.2 drive upgrade process for notebooks can vary greatly; we attempted to put together a general guide, showing how to upgrade a typical notebook. In our case, it was a Dell Latitude 7480, a 14-inch business-class model that isn’t all that unique in terms of its upgrade process. At the minimum, the process of uninstalling the M.2 drive itself, and re-installing it in your notebook should line up perfectly with this guide.
Experts in our forums are readily available to help you with any questions. The Hardware forum in particular is a good place to discuss the ins and outs of upgrading notebooks. And don’t forget to visit our Windows OS and Software forum for advice on installing Windows 10 or another operating system and software on your new M.2 drive. Happy upgrading!
SSD vs HDD | StorageReview.com
Most people now buy laptops for their computing needs and have to make the decision between getting either a Solid State Drive (SSD) or Hard Disk Drive (HDD) as the storage component. So which of the two is the better choice, an SSD or HDD? There’s no straight-forward answer to this question; each buyer has different needs and you have to evaluate the decision based on those needs, your preferences, and of course budget. Even though the price of SSDs has been falling, the price per gigabyte advantage is still strongly with HDDs. Yet, if performance and fast bootup is your primary consideration and money is secondary, then SSD is the way to go. For the remainder of this article, we will make a comparison of SSD and HDD storage and go over the good, the bad, and the ugly of both.
What is an SSD?
We’ll make no assumptions here and keep this article on a level that anyone can understand. You might be shopping for a computer and simply wondering what the heck SSD actually means? To begin, SSD stands for Solid State Drive. You’re probably familiar with USB memory sticks - SSD can be thought of as an oversized and more sophisticated version of the humble USB memory stick. Like a memory stick, there are no moving parts to an SSD. Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster. As an analogy, what’s quicker? Having to walk across the room to retrieve a book to get information or simply magically having that book open in front of you when you need it? That’s how an HDD compares to an SSD; it simply requires more physical labor (mechanical movement) to get information.
A typical SSD uses what is called NAND-based flash memory. This is a non-volatile type of memory. What does non-volatile mean you ask? The simple answer is that you can turn off the disk and it won’t “forget” what was stored on it. This is of course an essential characteristic of any type of permanent memory. During the early days of SSD, rumors floated around saying stored data would wear off and be lost after only a few years. Regardless, that rumor is certainly not true with today’s technology, as you can read and write to an SSD all day long and the data storage integrity will be maintained for well over 200 years. In other words, the data storage life of an SSD can outlive you!
An SSD does not have a mechanical arm to read and write data, it instead relies on an embedded processor (or “brain”) called a controller to perform a bunch of operations related to reading and writing data. The controller is a very important factor in determining the speed of the SSD. Decisions it makes related to how to store, retrieve, cache and clean up data can determine the overall speed of the drive. We won’t get into the nitty-gritty details for the various tasks it performs such as error correction, read and write caching, encryption, and garbage collection to name a few. Yet, suffice to say, good controller technology is often what separates an excellent SSD from a good one. An example of a fast controller today is the SandForce SATA 3.0 (6GB/s) SSD controller that supports burst speeds up to 550MB/s read and write speeds. The next gen SandForce 3700 family of controllers was announced in late 2013, and is quoted to reach a blistering 1,800MB/s read/write sequential speeds as well as 150K/80K random IOPS.
Finally, you may be wondering what an SSD looks like and how easy it is to replace a hard drive with an after-market device. If you look at the images below, you’ll see the top and undersides of a typically-sized 2.5” SSD. The technology is encased inside either a plastic or metal case and looks like nothing more than what a battery might:
SSD Top Side
SSD Bottom Side
The form factor of the SSD is actually the same as a regular hard drive. It comes in a standard 1.8”, 2.5”, or 3.5” size that can fit into the housing and connectors for the same-sized hard drives. The connector used for these standard sizes is SATA. There are smaller SSDs available that use what’s called mini-SATA (mSATA) and fit into the mini-PCI Express slot of a laptop.
What is an HDD?
Hard Disk Drives, or HDD in techno-parlance, have been around for donkey's years relative to the technology world. HDDs were first introduced by IBM in 1956 - yes folks this is nearly 60-year old technology, thank goodness vacuum tubes for TVs didn’t last so long! An HDD uses magnetism to store data on a rotating platter. A read/write head floats above the spinning platter reading and writing data. The faster the platter spins, the faster an HDD can perform. Typical laptop drives today spin at either 5400 RPM (Revolutions per Minute) or 7200RPM, though some server-based platters spin at up to 15,000 RPM!
The major advantage of an HDD is that it is capable of storing lots of data cheaply. These days, 1 TeraByte (1,024 gigabytes) of storage is not unusual for a laptop hard drive, and the density continues to grow. However, the cost per gigabyte is hard to calculate now-a-days since there are so many classes to consider, though it is safe to say that all HDDs are substantially cheaper than SSDs. As a comparison, the popular WD Black (1TB) goes for roughly $69 on most websites while the OCZ Trion 100 (960GB) and Samsung 850 EVO (1TB) SSDs go for $199 and $319 respectively, three to five times the price of the WD Black. So if you want cheap storage and lots of it, using a standard hard drive is definitely the more appealing way to go.
When it comes to appearance, HDDs essentially look the same from the outside as SSDs. HDDs predominantly use SATA interface. The most common size for laptop hard drives is the 2.5” form factor while a larger 3.5” form factor is used in desktop computers. The larger size allows for more platters inside and thus more storage capacity. Some desktop hard drives can store up to 6TB of data! Below is an example of what an HDD looks like using the Hitachi Deskstar 7K4000 4TB hard drive:

SSD Vs HDD Comparison
Now it’s time to do some comparisons and determine which might be best for your individual needs - SSD or HDD? The best way to compare items is a table with a side by side comparison of items in which a green box indicates an advantage:
If we tally up the checkmarks, the SSD gets 9 and HDD gets 3. Does that mean the that an SSD is three times better than an HDD? Not at all. As we mentioned earlier, it all depends on individual needs. The comparison here is just to lay out the pros and cons for both options. To aid you even more, here are some rules to follow when you decide which drive is best for you:
An HDD might be the right choice if:
- You need lots of storage capacity, up to 10TB
- Don’t want to spend much money
- Don’t care too much about how fast a computer boots up or opens programs - then get a hard drive (HDD).
An SSD might be the right choice if:
- You are willing to pay for faster performance
- Don’t mind limited storage capacity or can work around that (though consumer SSD now go up to 4TB and enterprise run as high as 60TB)
HDDs are still the popular choice for the majority of average consumers, usually choosing the HDD as the storage option in their new computer simply due to the much cheaper cost. However, more and more consumers desire top computing performance and are opting for an SSD inside their new setup or as an upgrade to their current one. As such, SSDs are well on their way to becoming the mainstream, standard storage mechanism, especially for laptops given the advantages they present for a mobile device (they are currently the default storage device in the Ultrabook category). That said, there will always be a market for both HDDs and SSDs. The advent of mSATA SSD devices and hybrid drives that include both SSD and HDD features is another option for consumers seeking a bit of the best of both worlds, but that’s a topic for another day!

SSD vs. HDD: What's the Difference?
The Choice Is Yours
Until recently, PC buyers had very little choice about what kind of storage to get in a laptop or desktop. If you bought an ultraportable, you likely had a solid-state drive (SSD) as the primary drive (C: on Windows, Macintosh HD on a Mac). Every other desktop or laptop form factor had a hard disk drive (HDD). Now, you can configure most systems with either an HDD or an SSD, or in some cases both. But how do you choose? We explain the differences between SSDs and HDDs (or hard drives), and walk you through the advantages and disadvantage of both to help you decide.
HDD and SSD Explained
The traditional spinning hard drive is the basic nonvolatile storage on a computer. That is, information on it doesn't "go away" when you turn off the system, as is the case with data stored in RAM. A hard drive is essentially a metal platter with a magnetic coating that stores your data, whether weather reports from the last century, a high-definition copy of the original Star Wars trilogy, or your digital music collection. A read/write head on an arm accesses the data while the platters are spinning.
An SSD does functionally everything a hard drive does, but data is instead stored on interconnected flash memory chips that retain the data even when there's no power present. The chips can either be permanently installed on the system's motherboard (as on some small laptops and ultraportables), on a PCI Express (PCIe) card (in some high-end workstations and an increasing number of bleeding-edge consumer systems), or in a box that's sized, shaped, and wired to slot in for a laptop or desktop's hard drive (common on everything else). These flash memory chips are of a different type than is used in USB thumb drives, and are typically faster and more reliable. SSDs are consequently more expensive than USB thumb drives of the same capacities.
Note: We'll be talking primarily about internal drives in this story, but almost everything applies to external hard drives as well. External drives come in both large desktop and compact portable form factors, and SSDs are gradually becoming a larger part of the external market.
A History of HDDs and SSDs
Hard drive technology is relatively ancient (in terms of computer history, anyway). There are well-known pictures of the infamous IBM 350 RAMAC hard drive from 1956 that used 50 24-inch-wide platters to hold a whopping 3.75MB of storage space. This, of course, is the size of an average 128Kbps MP3 file today, in the physical space that could hold two commercial refrigerators. The RAMAC 350 was only limited to government and industrial uses, and was obsolete by 1969. Ain't progress wonderful? The PC hard drive form factor standardized at 5.25 inches in the early 1980s, with the 3.5-inch desktop-class and 2.5-inch notebook-class drives coming soon thereafter. The internal cable interface has changed from serial to IDE (now frequently called parallel ATA, or PATA) to SCSI to serial ATA (SATA) over the years, but each essentially does the same thing: connect the hard drive to the PC's motherboard so your data can be processed. Today's 2.5- and 3.5-inch drives mainly use SATA interfaces (at least on most PCs and Macs), though some high-speed SSDs use the faster PCIe interface instead. Capacities have grown from multiple megabytes to multiple terabytes, more than a million-fold increase. Current 3.5-inch hard drives have capacities as high as 10TB, with consumer-oriented 2.5-inch drives maxing out at 4TB.
The SSD has a much shorter history. There was always an infatuation with nonmoving storage from the beginning of personal computing, with technologies like bubble memory flashing (pun intended) and dying in the 1970s and 1980s. Current flash memory is the logical extension of the same idea, as it doesn't require constant power to retain the data you store on it. The first primary drives that we know as SSDs started during the rise of netbooks in the late 2000s. In 2007, the OLPC XO-1 used a 1GB SSD, and the Asus Eee PC 700 series used a 2GB SSD as primary storage. The SSD chips on low-end Eee PC units and the XO-1 were permanently soldered to the motherboard. As netbooks and other ultraportable laptop PCs became more capable, SSD capacities increased and eventually standardized on the 2.5-inch notebook form factor. This way, you could pop a 2.5-inch hard drive out of your laptop or desktop and replace it easily with an SSD. Other form factors emerged, like the mSATA Mini PCIe SSD card, M.2 SSD in SATA and PCIe variants, and the DIMM-like solid-state Flash Storage in the Apple MacBook Air and MacBook Pro, but today many SSDs still use the 2.5-inch form factor. The 2.5-inch SSD capacity currently tops out at 4TB, but a 60TB version for enterprise devices like servers was released by Seagate in 2016.
Advantages and Disadvantages
Both SSDs and hard drives do the same job: They boot your system, and store your applications and personal files. But each type of storage has its own unique feature set. How do they differ, and why would you want to get one over the other?
Price: SSDs are more expensive than hard drives in terms of dollar per gigabyte. A 1TB internal 2.5-inch hard drive costs between $40 and $50, but as of this writing, an SSD of the same capacity and form factor starts at $250. That translates into 4 to 5 cents per gigabyte for the hard drive and 25 cents per gigabyte for the SSD. Since hard drives use older, more established technology, they will remain less expensive for the near future. Those extra hundreds for the SSD may push your system price over budget.
Maximum and Common Capacity: Although consumer-based SSD units top out at 4TB, those are still rare and expensive. You're more likely to find 500GB to 1TB units as primary drives in systems. While 500GB is considered a "base" hard drive in 2017, pricing concerns can push that down to 128GB for lower-priced SSD-based systems. Multimedia users will require even more, with 1TB to 4TB drives common in high-end systems. Basically, the more storage capacity, the more stuff you can keep on your PC. Cloud-based (Internet) storage may be good for housing files you plan to share among your phone, tablet, and PC, but local storage is less expensive, and you only have to buy it once.
Speed: This is where SSDs shine. An SSD-equipped PC will boot in less than a minute, and often in just seconds. A hard drive requires time to speed up to operating specs, and will continue to be slower than an SSD during normal use. A PC or Mac with an SSD boots faster, launches and runs apps faster, and transfers files faster. Whether you're using your computer for fun, school, or business, the extra speed may be the difference between finishing on time and failing.
Fragmentation: Because of their rotary recording surfaces, hard drives work best with larger files that are laid down in contiguous blocks. That way, the drive head can start and end its read in one continuous motion. When hard drives start to fill up, large files can become scattered around the disk platter, causing the drive to suffer from what's called fragmentation. While read/write algorithms have improved to the point that the effect is minimized, hard drives can still become fragmented. SSDs can't, however, because the lack of a physical read head means data can be stored anywhere. Thus, SSDs are inherently faster.
Durability: An SSD has no moving parts, so it is more likely to keep your data safe in the event you drop your laptop bag or your system is shaken about by an earthquake while it's operating. Most hard drives park their read/write heads when the system is off, but they are flying over the drive platter at a distance of a few nanometers when they are in operation. Besides, even parking brakes have limits. If you're rough on your equipment, an SSD is recommended.
Availability: Hard drives are more plentiful in budget and older systems, but SSDs are becoming more prevalent in recently released laptops. That said, the product lists from Western Digital, Toshiba, Seagate, Samsung, and Hitachi are still skewed in favor of hard drive models over SSDs. For PCs and Mac desktops, internal hard drives won't be going away completely, at least for the next few years. SSD model lines are growing in number: Witness the number of thin laptops with 256 to 512GB SSDs installed in place of hard drives.
Form Factors: Because hard drives rely on spinning platters, there is a limit to how small they can be manufactured. There was an initiative to make smaller 1.8-inch spinning hard drives, but that's stalled at about 320GB, since the phablet and smartphone manufacturers have settled on flash memory for their primary storage. SSDs have no such limitation, so they can continue to shrink as time goes on. SSDs are available in 2.5-inch laptop drive-sized boxes, but that's only for convenience. As laptops continue to become slimmer and tablets take over as primary platforms for Web surfing, you'll start to see the adoption of SSDs skyrocket.
Noise: Even the quietest hard drive will emit a bit of noise when it is in use from the drive spinning or the read arm moving back and forth, particularly if it's in a system that's been banged about or if it's been improperly installed in an all-metal system. Faster hard drives will make more noise than those that are slower. SSDs make virtually no noise at all, since they're non-mechanical.
Power: An SSD doesn't have to expend electricity spinning up a platter from a standstill. Consequently, none of the energy consumed by the SSD is wasted as friction or noise, rendering them more efficient. On a desktop or in a server, that will lead to a lower energy bill. On a laptop or tablet, you'll be able to eke out more minutes (or hours) of battery life.
Overall: Hard drives win on price, capacity, and availability. SSDs work best if speed, ruggedness, form factor, noise, or fragmentation (technically part of speed) are important factors to you. If it weren't for the price and capacity issues, SSDs would be the hands-down winner.
As far as longevity, while it is true that SSDs wear out over time (each cell in a flash memory bank can be written to and erased a limited number of times), thanks to TRIM command technology that dynamically optimizes these read/write cycles, you're more likely to discard the system for obsolescence (after six years or so) before you start running into read/write errors with an SSD. If you're really worried, there are several tools that monitor the S.M.A.R.T. status of your hard drive or SSD, and will let you know if you're approaching the drive's rated end of life. Hard drives will eventually wear out from constant use as well, since they use physical recording methods. Longevity is a wash when it's separated from travel and ruggedness concerns.
The Right Storage for You
So, does an SSD or HDD (or a hybrid of the two) fit your needs? Let's break it down:
HDDs• Enthusiast multimedia users and heavy downloaders: Video collectors need space, and you can only get to 4TB of space cheaply with hard drives.• Budget buyers: Ditto. Plenty of cheap space. SSDs are too expensive for $500 PC buyers.• Graphic arts and engineering professionals: Video and photo editors wear out storage by overuse. Replacing a 1TB hard drive will be cheaper than replacing a 500GB SSD.• General users: General users are a toss-up. Folks who prefer to download their media files locally will still need a hard drive with more capacity. But if you mostly stream your music and videos online, then buying a smaller SSD for the same money will give you a better experience.
SSDs• Road warriors: People who shove their laptops into their bags indiscriminately will want the extra security of an SSD. That laptop may not be fully asleep when you violently shut it to catch your next flight. This also includes folks who work in the field, like utility workers and university researchers.• Speed demons: If you need things done now, spend the extra bucks for quick boot-ups and app launches. Supplement with a storage SSD or hard drive if you need extra space (see below).• Graphic arts and engineering professionals: Yes, we know we said they need hard drives, but the speed of an SSD may make the difference between completing two proposals for your client and completing five. These users are prime candidates for dual-drive systems (more on that below).• Audio engineers and musicians: If you're recording music, you don't want the scratchy sound from a hard drive intruding. Go for quieter SSDs.
Hybrid Drives and Dual-Drive Systems
Back in the mid 2000s, some hard drive manufacturers, like Samsung and Seagate, theorized that if you add a few gigabytes of flash chips to a spinning hard drive, you'd get a so-called "hybrid" drive combining a hard drive's large storage capacity with the performance of an SSD, at a price only slightly higher than that of a typical hard drive. The flash memory acts as a buffer for frequently used files, so your system has the potential for booting and launching your most important apps faster, even though you can't directly install anything in that space yourself. In practice, hybrid drives work, but they are still more expensive and more complex than regular hard drives. They work best for people like road warriors who need both lots of storage and fast boot times. Since they're an in-between product, hybrid drives don't necessarily replace dedicated hard drives or SSDs.
In a dual-drive system, the system manufacturer will install a small SSD primary drive (C:) for the operating system and apps, and add a larger spinning hard drive (D: or E:) for storing files. This works well in theory; in practice, manufacturers can go too small on the SSD. Windows itself takes up a lot of space on the primary drive, and some apps can't be installed on other drives. Some capacities may also be too small. For example, you can install Windows on a SSD as small as 16GB, but there will be little room for anything else. In our opinion, 120GB to 128GB is a practical minimum size for the C: drive, with 256GB or more being even better. Space concerns are the same as with any multiple-drive system: You need physical space inside the PC chassis to hold two (or more) drives.
Last but not least, an SSD and a hard drive can be combined (like Voltron) on systems with technologies like Intel's Smart Response Technology (SRT). SRT uses the SSD invisibly to act as a cache to help the system more speedily boot and launch programs. As on a hybrid drive, the SSD is not directly accessible by the end user. SRT requires true SSDs, like those in 2.5-inch form factors, but those drives can be as small as 16GB in capacity and still boost performance; since the operating system isn't being installed to the SSD directly, you avoid the drive space problems of the dual-drive configuration mentioned above. On the other hand, your PC will need space for two drives, a requirement that may exclude some laptops and small-form-factor desktops. You'll also need the SSD and your system's motherboard to support the caching technology for this scenario to work. All in all, however, it's an interesting workaround.
The Storage of Tomorrow
It's unclear whether SSDs will totally replace traditional spinning hard drives, especially with shared cloud storage waiting in the wings. The price of SSDs is coming down, but they're still too expensive to totally replace the terabytes of data that some users have in their PCs and Macs. Cloud storage isn't free, either: You'll continue to pay as long as you want personal storage on the Internet. Local storage won't go away until we have ubiquitous wireless Internet everywhere, including in planes and out in the wilderness. Of course, by that time, there may be something better.

SSD Types and Form Factors – An SSD Primer
Our SSD close up today is going to examine the different SSD types and form factors common to the consumer.
This is the third paper in a series of recent articles that explained the benefits and components of a solid state drive and will go so far as to make up our SSD Beginners Guide. Each article is designed to be easily understood and will enable the reader to become proficient in every aspect of the SSD as it relates to their specific computing needs.
Our featured picture might seem a bit intimidating to most simply because the average consumer isn’t used to seeing, much less buying, anything that shows its circuitry and is not nicely packaged as the SSD in the middle is. It displays the OCZ RevoDrive 3×2 480GB PCIe card on the bottom, followed by the Crucial M4 512GB SATA 3 SSD with the Renice x3 mSATA 120GB SATA 2 SSD on top. A simple click on any of these links will bring you to the analysis we did of each on their release.
All three comprise of the main types or ‘form factor’ SSDs we may consider for purchase as they fit into the Ultrabook, notebook or desktop systems that we see available in any electronics store today. Don’t misconstrue my words because I’m definitely not saying that each will fit into any of the three type of computers and, in fact, if you take a close look you will see that the OCZ Revo 3×2 card is actually thicker than our Toshiba Z830 Ultrabook.
There are key differences in each form factor that go beyond size and placement alone which just may help you along in determining the solution for your specific need. Specific interface type, speed, and capacity are as similar to the group as a whole as they may be different given a specific need for the end user.
In as much as their are key differences, a key point that we learned in the last article, SSD Components and Make Up, is that each and every SSD has to have specific parts regardless of its form factor.
These parts are easily identifiable in all three shown here and are the interface which connects to your computer, processor which coordinates travel of information, circuit board and NAND flash memory which stores your data.
Just to keep things interesting, I thought I might throw in the OCZ RevoDrive Hybrid 1TB PCIe Hybrid SSD (which will be later discussed) and the OCZ 1.6TB Z-R4 PCIe SSD as both are recent releases and stand out in the crowd. The hybrid contains, not only a RevoDrive SATA 3 SSD for performance but also, a 1TB hard drive for capacity while the Z-R4 Drive is just about the fastest available PCIe card on the market as it has lightning speeds as fast as 2.8GB/s.
My absolute two favorite reviews that show our sites….creativity… just happen to be the RevoDrive Hybrid PCIe Review and the Runcore T50 SATA 3 mSATA SSD Review. The Hybrid review was based on a high school science experiment and even included Cold Play’s song, ‘The Scientist’ whereas the Runcore T50 review drew comparison to that SSD and the 1969 Ford Mustang with the ‘monster’ 429 Boss engine.
For those new to our reviews, a quick click on any picture will bring up a much better high resolution version whereas a click on any word that is shown in orange will bring you directly to the article discussed.
SSD ve Solid State Disk Modelleri
SSD ve Solid State Disk Modelleri
Son yıllarda hayatımıza giren SSD (Solid State Disk), bilinen depolama donanımlarının yerini alıp aynı işi daha hızlı bir biçimde gerçekleştiren yeni bir teknolojidir.
SSD'nin hard disklere artıları; hızlı başlangıç, hızlı veri ulaşımı, sessiz çalışma özelliği, minimum enerji tüketimi, daha fazla mekanik dayanıklılık, daha az yer kaplama ve yazma-okuma işlemlerinde minimum hatadır.
Bilgisayarlarda ve çeşitli mobil platformlarda kullanılan ve her şeyi kaydetmeye yarayan diskler, bu özellikleri ile önemli bir rol üstleniyor. Bu disk çeşitlerinden birisi olan Solid State Disk (SSD) ürünleri daha yüksek performans seçenekleri ve verim isteyen kullanıcılar için ön plan açıkıyor. SSD'ler HDD'lere göre daha soğuk çalışması, daha az gürültü çıkarması ve daha az güç kullanımı ile gündelik işlerde veya oyun amaçlı kullanımlarda kullanıcılar tarafından daha çok tercih ediliyor. Sistem kaynaklarını daha az kullanması ile de diğer donanımlarında çalışma ömrüne katkı sağlıyor. Bu hız ve verime ulaşmak için ise birçok markanın farklı modelleri bulunuyor. Bu markalar arasında Samsung, Sandisk, Kingston, Toshiba ve İnteliyi malzeme ve yüksek performans ile ön plana çıkıyor. Bu markaların modelleri ile rahat ve hızlı kullanım mümkün oluyor.
SSD'ler modellerine göre farklı hafıza kapasiteleri ile üretiliyor. Kullanım tercihlerine göre birçok model bulunuyor. En düşüğü genelde 32 GB'tan başlamak üzere; 64 GB,120 GB,128 GB ile 1 TB arasında SSD modellerinden, ihtiyacınıza göre seçim yapabilmek mümkün oluyor. Diğer bir model farkı ise okuma ve yazma hızları. Her ne kadar standart olarak SSD'ler yüksek hızlara sahip olsalar da bazı modellerin yazma ve okuma hızları farklı olabiliyor.Okuma hızları saniyede 400 MB'tan başlayarak 800 MB gibi rakamlara ulaşırken, yazma hızları da 150 MB'tan başlayarak yine 800 MB gibi rakamlara ulaşabiliyor. Tercihinize göre bu rakamlardan istediğinizi seçebilir ve SSD'nizden daha yüksek performans alabilirsiniz. Uyumlu yapısı ile de SSDürünlerini taşınabilir cihazlarında da rahatlıkla kullanabilir, bu cihazlar ile de yüksek performanslara ulaşabilirsiniz. HDD'lere göre daha ince ve ergonomik tasarımı ile bilgisayarlarınızda çok fazla yer kaplamadan SSD hard diskleri kullanabilirsiniz.
