Finding the best SSD or solid-state drive for your specific system and needs is key if you want the best gaming PC or laptop, or even if you just want a snappy productivity machine. A slow storage drive often leads to a big bottleneck, forcing your processor (even if it's one of the best CPUs) to idly twiddle its clock cycles, waiting for data to crunch. To speed up your writes and reads, you need a speedy SSD. To figure out which is the best SSD, we test dozens of drives each year and highlight the best drives here.

Picking the Best SSD for You

As drives like Adata's Falcon M.2 and the Intel 665p undercut mainstream drives on the slower SATA interface (which was originally designed for hard drives), we could be witnessing the beginning of the end of our old friend, Serial ATA. But companies are still doing new things with SATA, like Team Group's cavernous 15.3 TB drive. Existing SATA drives will have to continue to get more affordable in order to at least compete on price, since they can't hope to keep up with newer NVMe drives on performance.

Blazing-fast PCIe 4.0 M.2 SSDs have become common, and will likely become more mainstream now that Intel has finally joined the PCIe 4.0 support party with Z590 and 11th Gen Rocket Lake CPUs. These drives indeed up sequential speeds dramatically (thanks to a doubling of the PCIe bus bandwidth), making them the best SSDs for those who need the fastest speed possible. For example, the Samsung 980 PRO can read and write at 7,000 and 5,000 MBps respectively, and drives based on Phison's second-gen controller promise up to 7,400 / 7000 MBps sequential speeds.

But to make use of that speed today, you'll need either an X570 motherboard or  B550 board on the AMD side, or a new Z590 motherboard from Intel.

All that said, keep in mind that in many ways, beyond the obvious bump in sequential performance, users might not see much in the way of real-world benefits from these faster drives. It really depends on how heavily you use your drive.

Now also might be a great time to buy that SSD upgrade you've been putting off. Because a new cryptocurrency called Chia, which involves 'farming' plots on hard drives, rather than 'mining' on GPUs, recently began trading and has already pointed toward drive shortages and price increases in Asia and elsewhere. If the value of Chia continues to climb, we could soon be in for a storage shortage or, at the very least, significant price increases as demand skyrockets.

Quick Shopping Tips

When choosing an SSD, consider the following:

  • Pick a compatible interface (M.2 PCIe, SATA, Add-in Card): Look at your user manual or a database like the Crucial Memory Finder to determine what types of SSD your computer supports.
  • 512GB to 1TB: Don't bother getting an SSD smaller than 256GB. 512GB provides a good balance between price and capacity if you're on a tight budget. But 1TB drives are getting significantly cheaper and 2TB drives are now more affordable than ever.
  • SATA is slowest: SATA isn't as fast as M.2 PCIe or a PCIe add-in card, but the majority of desktops and many laptops can take 2.5-inch SATA drives and many doing typical mainstream tasks users won't notice the difference between a good recent SATA drive and a faster PCIe model anyway.

Below, you'll find our recommendations for drives with all three major interfaces.

M.2 PCIe NVMe Drives

These small, rectangular drives look like sticks of RAM, only smaller. They are usually 80mm long by 22mm wide, described as size 2280, but some may be shorter or longer, so make sure you get one that matches your slot. You can get M.2 drives that support SATA, but most modern desktops and laptops with M.2 slots support the faster PCIe NVMe standard.

SK hynix’s Gold P31 touts market leadership as the first retail SSD product to launch with 128L NAND flash. With SK hynix’s newest NAND reaching incredible bit density, the Gold P31 hits the market at very low pricing. Listed at just $75 and $135 for the 500GB and 1TB models, respectively, the Gold P31 is a fantastic value that will make you think twice about spending that extra $25-$50 on the Samsung 970 EVO Plus.

SK hynix’s Gold P31 is very well suited for those looking to increase their laptop storage not only to gain capacity but to gain battery life, too. While Adata’s SX8200 Pro performs well against the Gold P31 in benchmarking, the SK hynix is much more power-efficient, which will lead to longer off-the-charger sessions. But, while the Adata is the better buy for desktops and the SK hynix is best for laptops, the Gold P31's much stronger write performance and ultra-high efficiency make it the better well-rounded choice for many users.

Laptop users who don’t need more than a terabyte of storage and prioritize battery life should definitely put the new SK hynix Gold P31 at the top of their drive list.

We're quite impressed with the Samsung 970 EVO Plus. Like the WD Black SN750, Samsung’s drive carries over the same controller as its predecessor. But instead of refreshing it with the same flash, Samsung decided to switch things up a bit with its new 9x-layer flash. Just as the flash is stacked to new heights, performance hits new highs, too. The resulting drive is exactly what its name says: a big Plus.

As the first widely-available retail SSD to hit the market with Samsung's latest 9x-layer flash, the Samsung 970 EVO Plus delivers the same performance as the 970 EVO, plus more. The drive consistently proved that it has some of the strongest write performance on the market and can handle tough workloads. It even beat out Samsung’s own 970 PRO in a few tests, which is quite the feat considering the PRO slots in as Samsung's workhorse for workstation-class applications.

Competitive pricing, performance & efficiency
Single-sided form factor
5-year warranty & class-leading endurance ratings
 Head spreader is very malleable

Team Group’s T-Force Cardea Zero Z340 SSD isn’t much more expensive than most entry-level M.2 SSDs. Still, with the latest mainstream hardware under the hood, it’s a good choice for gamers looking to stretch their budget a bit for something more consistent and reliable.

The drive offers a good bang-for-your-buck upgrade or a good option for those planning their next PC. It’s a responsive SSD that not only offers up multi-gigabyte performance; it's rated for killer write endurance over its five-year warranty period. Plus, it comes with a slick graphene and copper label to handle heavy workloads without overheating, even without airflow in our test system. If you want to use a heatsink with your M.2, the label won’t prevent it like the heatsinks on some SSDs, like Patriot’s Viper series.

In our testing, we found that the combination of the Phison E12S controller and Micron 96L flash performed fairly well. Notably, the drive delivers faster performance than the older hardware powering the Seagate FireCuda 510 and is more efficient, too. But it isn’t the best of the best.

Solid performance and class-leading endurance
Attractive RGB lighting and heatsink
Available in capacities up to 2TB
Small write cache
Some lighting settings may affect performance
No SSD toolbox or cloning software

When we first took a look at the Viper VPR100, we were a bit concerned about its performance. Not only was it rated lower than most Phison E12-based SSDs, but the company states it will perform slower under various RGB settings. But, when we ran it through its paces with various lighting settings, the drive displayed no such issue with our ASRock X570 Taichi testbed. In fact, it even outperformed the MyDigitalSSD BPX Pro at times with the default lighting enabled, beating its rated specs.

The integrated heatshield not only adds quite a bit to the aesthetics of the Viper VPR100, but it also keeps the SSD cool under any workload. The LED’s didn’t add any significant heat output, either. So, no matter what your style is, you won’t have to sweat over your choice. If you're building an all-RGB rig or just a new gaming system that you want to also add a bit of color to, the Viper VPR100 will definitely light things up.

Sabrent’s 8TB Rocket Q slots in as the industry’s highest-capacity M.2 NVMe SSD. The pint-sized monster is obviously best suited for the data hoarder on the go, but at $1,500, it’ll set you back about as much as a decent gaming laptop. The drive doesn't just push capacity to the highest we've seen with a slim M.2 SSD; it also impresses with great performance and efficiency, thanks to the new Phison E12S controller and 96-Layer QLC flash.

QLC flash does have its downfalls, like lower endurance and slower write performance after the SLC write cache gets filled up during large file transfers, but the Phison E12S controller helps push the Rocket Q to the fastest performance we've seen from a QLC drive.

Samsung’s 980 is an inexpensive M.2 SSD that lacks DRAM, but it packs the company’s fastest flash yet. While shackled down by a PCIe 3.0 x4 interface, Samsung’s 980 may not be as fast as the Gen4 speed spewing monster that is the 980 Pro, but it is still a very responsive DRAM-less M.2 NVMe SSD thanks to its optimized design. Without DRAM, the SSD performs efficiently, keeps pace with many of the best PCIe Gen3 SSDs, and still boasts respectable endurance ratings. Sustained write performance may not be as strong as the WD Blue SN550’s, but with a cache that is over 13x larger, Samsung’s 980 shouldn’t slow down to slower than rated speeds often and should offer a more responsive user experience for the majority of its life.

11. WD Blue SN550

Best Value DRAMless M.2 SSD

Capacities: 250GB, 500GB, 1TB | Form Factor: M.2 2280 Single-sided | Transfer Interface/Protocol: PCIe 3.1 x4 / NVMe 1.3 | Sequential Reads/Writes: 2,400 MBps / 1,750 MBps | Warranty/Endurance: 5 Years / Up to 600 TBW

Competitive Performance
Affordable and efficient
5-year warranty
1TB maximum capacity
Small SLC cache
Power optimization on desktops could be better

With a single-sided form factor, the Blue drive is also compact and slim for any M.2 2280 application. And, with a low average and well-regulated maximum power consumption, the WD Blue SN550 will pair nicely with an external NVMe adaptor, too, if you’re looking for something on the go. The SN550 delivers a responsive experience and is a quality SSD backed by thousands of validation tests. With a five-year warranty and plenty of endurance, the Blue SN550 is well worth considering – even if low cost isn't your main priority.

WD’s Blue SN550 is one of the most consistent-performing low-cost NVMe SSDs available. Even though it has a small SLC write cache, its slowest performance will still remain acceptable when you hammer it with heavy writes. In our testing of the 1TB model, it even responds faster to applications and most consumer workloads than the WD Black SN750, including loading up your favorite games.

Best Low-Capacity Add-in-Card SSD: Intel Optane SSD 900P 

17. Intel Optane SSD 900P

Best Low-Capacity Add-in-Card SSD

Capacities: 280GB, 480GB | Form Factor: Half-Height, Half Length / U.2 15mm | Transfer Interface/Protocol: PCIe 3.0 x4 / NVMe 1.3 | Sequential Reads/Writes: 2,500 MBps / 2,000 MBps | Warranty/Endurance: 5 Years / Up to 8.76 PBW

Leading random read performance
Exceptional mixed workload performance
Endurance up to 8.76 PBW
AES 256bit encryption support
SSD Toolbox included
Extremely high cost per GB
Lower sequential performance than NAND based SSDs
Limited capacities options

There aren’t many options for AICs in the consumer market as the M.2 form factor has become so popular. At a capacity of 480GB and a nearly absurd price of about $1/GB, the Intel Optane SSD 900P is your top-performing option. Powered by a custom Intel NVMe controller and their 3D XPoint memory, the 900P is one of the fastest performing SSDs on the market. Unlike the 905P, it comes in an AIC form factor at the 480GB capacity, not just U.2. But while its random performance is better than anything else we’ve seen before, its sequential performance is rather underwhelming when compared to some of the fastest NAND-based SSDs. Its power consumption is also much higher than any competitor. Unfortunately, Intel has decided to end its Optane lineup for desktop PCs, so we won't see new models in the future and stock will slowly dwindle on the existing models. That means you'll need to buy one today if you plan on going the Optane route.

    About the MX500... "but the 500GB looks really good at just $139.99"

    You might want to double check prices when cutting and pasting.

    I would think the Samsung 860 EVO 500gb would have grabbed the spot for best SATA as you can get it for $99 (500gb) and it's quite fast. I doubt the pro is fast enough to justify the cost over the EVO version.

    Thanks for bringing this to our attention. It looks like the wires got crossed on our pricing widget. We're implementing a fix. Stand by.

    I recently ordered a 1TB 2.5" WD Blue SSD for ~$139 on a Shellshocker. Hopefully it arrives soon!

    Was that the M.2 or the SATA version?
