Most people will never stress their SSD this hard, though. All that performance comes at a premium, though. Be aware of what NVMe drives deliver before you buy in. To get the most out of an NVMe drive, you want to run your operating system on it, so you must have a system that recognizes the drive and can boot from it. PCs purchased during the past year or two should have no problem booting from an NVMe drive, but support for that can be iffy in older motherboards. Do a Google search for your motherboard and see if it supports booting from NVMe.
You may need to install a BIOS update for your board. Capacity and price are important, of course, and a long warranty can alleviate fears of premature data death. Most SSD manufacturers offer a three-year warranty, and some nicer models are guaranteed for five years. We go into deeper details and buying advice in our guide on which SSD you should buy. Not all of them, though. Do you need an SSD?

Also great. Everything we recommend. How many gigabytes do you need? Why you should trust us. Who this is for. What kind of SSD do you need?
How we picked and tested. Performance: Speed is the main reason to buy an SSD, after all. We checked reviews to make sure that the drives hit their advertised performance figures and that they would continue to feel speedy over time. Capacity at or above GB: For most people, GB offers the best mix of value, capacity, and speed.
Durability: You can write to flash-memory cells only so many times before they wear out—manufacturers express this as TBW, or the minimum number of terabytes that can be written before the drive will fail. This rating is higher for larger drives since they have more flash-memory cells to write to; for GB drives, a rating of TBW is fairly common. Although most people will never get anywhere near that limit during the normal lifetime of a drive, higher endurance is a plus.
Software: The best SSDs come with free data-migration software that can help you transfer your operating system and apps to a new drive without having to start fresh.
Your operating system can still encrypt drives without such support, but that results in a slightly greater hit to performance. Our pick: Samsung SSD Faster but still affordable options. Performance and endurance figures are for the GB version of each drive. But reviewers note that it can run hot, so it might not be the best fit for a laptop. A faster drive for the PlayStation 5. While the above advice is true in a general sense, some drives can buck trends, and technology is always advancing and changing the landscape.
If battery life is key to your drive-buying considerations, be sure to consult the power consumption testing we do on every SSD we test. Think of the controller as the processor of your drive. It routes your reads and writes and performs other key drive performance and maintenance tasks. It can be interesting to dive deep into specific controller types and specs. Some of them are far less common than they used to be, and some are becoming the de facto standard.
All flash memory has a limited life span, meaning after any given storage cell is written to a certain number of times, it will stop holding data. As the years pass and cells start to die, the drive will move your data off the worn-out cells to these fresh new ones, thereby greatly extending the usable lifespan of the drive.
The flash in SSDs used to be arranged in a single layer planar. As time progresses, drive makers are stacking more and more layers on top of each other, leading to denser, more spacious, and less-expensive drives. At this point, the vast majority of current-generation consumer SSDs are made using some type of 3D storage. These days, many drives use layer or layer NAND, and technologies to add more layers are always in the works. While Micron was heavily involved in the development of 3D Xpoint, and intends to eventually bring it to market, as of this writing, Intel is the only company currently selling the technology to consumers, under its Optane brand.
Optane drives have much potential, both on the ultra-fast performance front and as a caching option for those who want the speed of an SSD for frequently used programs but the capacity of a spinning hard drive for media and game storage. But Intel announced in early that it was discontinuing standalone Optane drives.
So unless and until Micron sees fit to bring Xpoint to consumers, the technology seems to be at a dead-end for enthusiasts looking for extreme storage. But as with most PC hardware, there are diminishing returns for mainstream users as you climb up toward the top of the product stack. Matt Safford. Topics Components. See all comments Very nice article for beginners, clear and to the point, practical: bravo!
What about having onboard DRAM cache, at least for lookup tables? Or is that a controller detail that will be clearly expressed in performance graphs? I concur. Very good article for average computer user.
