Switching to a solid-state drive is the best upgrade you can make for your PC. These wondrous devices obliterate long boot times, speed up how fast your programs and games load, and generally makes your computer feel fast. But not all solid-state drives are created equal. The best SSDs offer solid performance at affordable prices—or, if price is no object, face-meltingly fast read and write speeds.

Many SSDs come in a 2.5-inch form factor and communicate with PCs via the same SATA ports used by traditional hard drives. But out on the bleeding-edge of NVMe (Non-Volatile Memory Express) drives, you’ll find tiny “gumstick” SSDs that fit in M.2 connections on modern motherboards, SSDs that sit on a PCIe adapter and slot into your motherboard like a graphics card or sound card, futuristic 3D Xpoint drives, and more. Picking the perfect SSD isn’t as simple as it used to be.

That’s where this guide comes in. We’ve tested numerous drives to find the best SSDs for any use case. Let’s take a look at PCWorld’s top picks, and then dive into what to look for in an SSD. Quick note: This roundup only covers internal solid-state drives. Check out PCWorld’s guide to the best external drives if you’re looking for a portable storage solution.

Updated March 11, 2019 to add the Crucial P1 NVMe SSD review (available on Amazon). It's very affordable and a good choice for mainstream consumers, but stick to smaller file sizes—its performance takes a nosedive when it runs out of cache. Read our review

Latest SSD news 

  • Intel and Micron announced that they’ll stop jointly developing 3D XPoint in the first half of 2019. 3D XPoint is the revolutionary storage technology inside Intel’s blazing-fast Optane SSDs. Both plan to develop the technology independently, however.
  • Intel discontinued desktop “Core+” bundles that packaged Core processors with Optane Memory drives mid-January. Laptop versions of the bundles will continue to be sold.

Best SSD for most people

The Samsung 850 EVO served as our go-to SSD recommendation ever since it debuted in 2014, but after a long reign at the top, the company replaced the legendary drive with the Samsung 860 EVO in 2018. The replacement isn’t quite as revolutionary as its predecessor but nevertheless claims the throne as the best SSD for most people.

The Samsung 860 EVO isn’t the fastest SSD you can buy—that honor goes to advanced drives that transfer data over PCI-E rather than the traditional SATA interface—but it’s the fastest triple-layer cell (TLC) SATA drive we’ve tested, albeit by a small margin. More importantly, it’s solved the slow write performance plaguing many other SSDs that use TLC NAND chips. We copied a whopping 80GB of data in one test and the EVO stayed strong the entire time, rather than bogging down after exceeding its cache.

Costs crept slightly upwards with the new generation of hardware, but the Samsung 860 EVO still offers a compelling blend of price, performance, and capacity that few SSDs can match, backed by a long five-year warranty and Samsung’s superb Magician SSD software for easy-peasy drive installation and maintenance. And as a 2.5-inch SATA-based drive, the Samsung 860 EVO should have no problems slipping into most desktops or laptops, unlike exotic M.2 and PCIe SSDs. (The drive is also available in the M.2 form factor however.)

The 500GB Samsung 860 EVO (available on Amazon) is probably the best option for most people, but it’s also available in 250GB, 1TB, 2TB, and 4TB models. Prices for SSDs start to get staggering once you hit 1TB or more of capacity, though. Many people might be better off buying the 500GB version and pairing it (if need be) with a high-capacity traditional hard drive like the Western Digital Blue lineup ($50 for 1TB on Amazon).

But other SSDs are challenging the Samsung 860 EVO. The Sandisk Ultra 3D ($70 for 500GB on Amazon) is another solid option. The Sandisk Ultra 3D’s three-year warranty lags behind the five-year warranty of the Samsung drives, though. The WD Blue 3D NAND SATA SSD ($68 on Amazon) is essentially the same SSD as the Sandisk Ultra 3D, but sold with a different label and in another form factor (M.2).

Seagate’s Barracuda SSD, meanwhile, is even faster than the 860 EVO in many situations but suffers from occasional brief, bizarre performance dips. That’s a bit unsettling, but Seagate offers a generous five-year warranty with the drive. It’s available in 250GB for $53, 500GB for $73, 1TB for $140, and 2TB for $300

Samsung also offers the Samsung 860 Pro, but the Samsung 860 EVO is nearly as fast. The only reason to opt for the Pro model is if you you’re concerned about longevity or write far more data daily than the average user, as it offers a best-in-class endurance rating. You pay for the peace of mind, though. A 256GB model costs $90 on Newegg, while a 512GB model sells for $150. You’ll also find 1TB2TB, and 4TB Samsung 860 Pro drives available—the latter for a staggering $1,000. 

Best budget SSD

If you’re looking for a solid, easy-to-install SATA SSD but don’t want to spend a lot of money, check out the Samsung 860 QVO. This budget-friendly drive is an excellent everyday performer when both reading and writing data, and at $140 for a 1TB model on Amazon, it offers plenty of storage space. Samsung also plans a 2TB model for $300 and a 4TB model for $500, though neither is currently available at retail.

Samsung managed the feat by designed the 860 QVO around quad-level cell NAND, making it one of the first QLC SSDs on the market along with the NVMe-based Intel 660p. The new technology lets drive makers stuff SSDs with hard drive-like levels of capacity while simultaneously maintaining those juicy SSD speeds we all love so much—most of the time. If you exceed the 860 QVO’s cache, speeds plummet to hard drive-like levels too. Fortunately, that limitation doesn’t kick in unless you’re shifting very large amounts of data (and Intel’s QLC drive suffers the same fate). Our tests moved around 42GB of data before blowing past the cache and seeing those slower speeds.

That might be an issue for some specialized workloads, but when you consider the drive’s overall capabilities and mouthwatering price-per-gigabyte, it’s a stellar low-cost option for many people, especially if you’re considering the larger 2TB and 4TB capacities.

Best NVMe SSD

If performance is paramount, the Samsung 970 Pro is the best NVMe SSD you can buy, backed by Samsung’s excellent Magician SSD management software—but most people should buy Adata’s XPG SX8200 Pro instead. This ludicrously fast drive roars past SATA-based SSDs in sustained read/write tests and delivers better performance as the chart-topping 960 Pro. But it does so for significantly less cash: 256GB for $75 on Amazon, 512GB for $120, and the 1TB model we tested for $215. Wow. 

The Samsung 970 EVO Plus is an excellent alternative, delivering up to 42 percent better performance than the older 970 EVO it replaced, and at far lower prices. The 970 EVO Plus is available in 250GB, 500GB, and 1TB flavors for a $90, $130, and $250, respectively. That’s astoundingly good bang-for-buck with a drive this potent.

The WD Black SN750 is the successor to the WD Black 3D SSD that reigned as our top pick for most of 2018. It’s just a hair slower than the Samsung 970 EVO Plus (and nearly as fast as the 970 Pro), but you’ll never notice the difference, and the WD drive handles extremely large file transfers better. It’s one of the best combinations of price and performance you can find in an NVMe drive, at $80 for 250GB, $130 for 500GB, $250 for 1TB, and $400 for 2TB on Amazon.

Fastest SSD

If performance is paramount and price is no object, Intel’s Optane SSD 905P is the best SSD you can buy, full stop. The drive doesn’t use traditional NAND technology like other SSDs; instead, it’s built around the futuristic 3D Xpoint technology developed by Micron and Intel. Hit that link if you want a tech deep-dive, but in practical terms, the Optane SSD 900P absolutely plows through our storage benchmarks and carries a ridiculous 8,750TBW (terabytes written) rating, compared to the roughly 200TBW offered by many NAND SSDs. If that holds true, this blazing-fast drive is basically immortal—and it looks damned good, too.

But you pay for the privilege of bleeding edge performance. Intel’s Optane SSD 905P costs $550 for a 480GB version and $1,279 for a 1.5TB model, with several additional options available in both the U.2 and PCI-E add-in-card form factors. That’s significantly more expensive than even NVMe SSDs—and like those, the benefits of Intel’s SSD will be most obvious to people who move large amounts of data around regularly. And the Optane SSD 900P actually uses the NVMe protocol to communicate with your PC, so you’ll need to meet some additional criteria to be able to boot from it—which we’ll cover next.

The step-down Intel Optane SSD 900P is like a miniature version of the 905P, still beating out traditional SSDs (albeit by a smaller margin) at lower capacities and prices—though at  $285 for a 280GB version and $600 for a 480GB model, it’s still drastically more expensive than most NVMe drives.

The Intel SSD 800P ($129 for 58GB, $199 for 118GB on Newegg) isn’t anywhere near as compelling a purchase despite being far more affordable. It still offers best-in-class longevity and very fast random file access, but the 800P delivers mundane results in other performance areas, and it’s crippled by low capacities and sky-high prices. Grab one of our other top SSD picks instead.

NVMe SSD setup: What you need to know

Be aware of what NVMe drives deliver before you buy in. Standard SATA SSDs already supercharge boot times and loading times for PCs, and for a whole lot cheaper. You’ll get the most use from NVMe drives, be it in a M.2 form factor like the Samsung 960 Pro or a PCIe drive, if you routinely transfer data, especially in large amounts. If you don’t do that, NVMe drives aren’t worth the price premium.

If you decide to buy an NVMe SSD, make sure your PC can handle it.  This is a relatively new technology, so you’ll only be able to find M.2 connections motherboards from the past few years. Think AMD Ryzen and mainstream Intel chips from the Skylake era onward, for the most part. NVMe SSDs that were mounted on PCIe adapters were popular in the technology’s early years, before M.2 adoption spread, but they’re rarer now. Make sure you’re actually able to use an NVMe SSD before you buy one, and be aware that you’ll need 4 PCIe lanes available in order to use it to its full potential.

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. If your hardware can’t boot from an NVMe SSD, your machine should still be able to use it as a secondary drive.

What to look for in an SSD

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. But unlike the olden days of SSDs, modern drives won’t wear out with normal consumer usage, as Tech Report tested and proved years ago with a grueling endurance test.

The biggest thing to watch out for is the technology used to connect the SSD to your PC.

      • SATA: This refers to both the connection type and the transfer protocol, which is used to connect most 2.5-inch and 3.5-inch hard drives and SSDs to your PC. SATA III speeds can hit roughly 600MBps, and most—but not all—modern drives max it out. (More on that in the next section.)
      • PCI-E: This interface taps into four of your computer’s PCIe lanes to blow away SATA speeds, to the tune of nearly 4GBps over PCIe gen. 3. Those sort of face-melting speeds pair nicely with supercharged NVMe drives. Both the PCIe lanes in your motherboard and the M.2 slot in your motherboard can be wired to support the PCIe interface, and you can buy adapters that allow you to slot “gumstick” M.2 drives into a PCIe lane.
      • NVMe: Non-Volatile Memory Express technology takes advantage of PCIe’s bountiful bandwidth to create blisteringly fast SSDs that blow SATA-based drives out of the water. Check out PCWorld’s “Everything you need to know about NVMe” for a nitty-gritty deep-dive.
      • M.2: This is where things get tricky. Many people assume M.2 drives all use NVMe technology and PCIe speeds, but that’s not true. M.2 is just a form factor. Sure, most M.2 SSDs use NVMe, but some still stick to SATA. Do your homework. Many modern Ultrabooks rely on M.2 for storage.
      • U.2 and mSATA: You may also stumble across mSATA and U.2 SSDs, but both motherboard support and product availability are rare for those formats. Some older Ultrabooks included mSATA before M.2 became popular, and drives are still available if you need them.

Speed matters, of course, but as we said most modern SSDs saturate the SATA III interface. Not all of them, though.

SSDs vs. hard drives

Do you need an SSD? “Need” is a strong word, but we heartily recommend that everyone upgrade to an SSD. Solid-state drive speeds blow even the fastest mechanical hard drives out of the water. Simply swapping the hard drive in your old laptop or desktop out for an SSD can make it feel like a whole new system—and a blazing fast one at that. Buying an SSD is easily the best upgrade you can make for a computer.

Intel

Intel Optane accelerates hard drives.

SSDs cost more per gigabyte than mechanical hard drives, though, and thus aren’t often available in ultra-high capacities. If you want speed and storage space, you can buy an SSD with limited space (like the 128GB Crucial BX300) and use it as your boot drive, then set up a traditional hard drive as secondary storage in your PC. Place your programs on your boot drive, stash your media and other files on the hard drive, and you’re ready to have your cake and eat it too.

Alternatively, Intel’s new Optane drives blend both worlds. These tiny, affordable M.2 drives are designed to pair with a hard drive in your system and act as a cache, speeding up the most-used programs on your PC. Intel’s tech can truly supercharge your everyday experience, but once you blow past the M.2 drive’s 16GB or 32GB of cache, you’re back to pokey hard drive speeds. Optane also has strict configuration and supported hardware requirements. Check out PCWorld’s Intel Optane memory review for the full details.

At a Glance

Adata's XPG SX8200 Pro is as fast as Samsung's mighty 970 Pro the majority of the time, and significantly cheaper. A great drive at a great price.

Pros

  • A great performer
  • Significantly cheaper than the competition
  • Attractive heat spreader/cover included for gamers

Cons

  • Drops from 1.8GBps to 1GBps on long writes

The Intel SSD 905P is one of the fastest NVMe drives we've tested, and one of the most expensive. But that's because it's rated to be very durable. If you write a lot of data, that's a selling point worth considering.

Pros

  • Excellent overall performance
  • Exceptional small file, queued, and threaded performance
  • Incredible longevity (claimed)

Cons

  • Extremely expensive

The Western Digital Black 3D NVMe SSD is as fast as Samsung's 960 Pro, but it costs a lot less. In fact, it's only slightly more expensive than entry-level drives. It's the drive that smart buyers should go for.

Pros

  • Top-notch performance
  • Priced more like a budget NVMe SSD than a premium model
  • Five-year warranty

Cons

  • Boring label
  • Easy to confuse with an older WD Black SSD that was also M.2/NVMe

This is the fastest M.2 NVMe SSD available to the end-user, as well as the priciest. Based on fast-writing MLC (2-bit) NAND, it's also long-lived. All things considered, it's the one you want if you have the wherewithal.

Pros

  • Fastest M.2 NVMe SSD available
  • Long warranty and high TBW rating

Cons

  • Considerably more expensive than the competition

If you want the fastest, longest lasting storage for your PC, Intel's SSD 900P with its Optane memory is it. It's especially faster with applications such as video and audio content creation and editing that can thread multiple writes.

Pros

  • Blazingly fast
  • 100 times the rated endurance of NAND SSDs
  • Stunning IOPs numbers

Cons

  • Rougly twice the price of the average NVMe/PCIe SSD

The Sandisk Extreme Pro NVMe is a worthy competitor to the Samsung 960 Pro performance-wise, and blows its doors off on price. Top-tier performance at a budget price pretty much says it all.

Pros

  • High-end NVMe performance
  • Near budget-level in price

Cons

  • Slower than the rival 960 Pro without caching involved

In the 2TB and 4TB capacities, this SATAa 6Gbps SSD is a lot cheaper than the competition. It's also a very fast reader, and a fast writer—until it runs out of cache. At the 1TB level however, there are cheaper drives that don't slow down even when writing large data sets.

Pros

  • Great cost per gigabyte in larger capacities
  • Available in up to 4TB capacity
  • A svelte 7mm thin

Cons

  • Sustained write speed plummets to 70MBps after secondary cache is exhausted

The Samsung 970 Evo Plus is faster and cheaper than the 970 Evo Pro, and easily one of the better performers in the low end of the market. The five-year warranty for the Evo Plus is also very nice to have.

Pros

  • Fast everyday performance
  • More affordable than the 970 Pro
  • Write performance drop is mild compared to that of other TLC drives

Cons

  • Slows to 875MBps during long writes

The Samsung 860 EVO delivers performance every bit as good as its MLC rivals. It's a worthy competitor for the WD Blue 3D and Sandisk 3D, two other TLC drives that are undoing TLC's weak reputation.

Pros

  • Excellent performance on a par with MLC drives
  • Very affordable
  • Very fast with small queued writes

Cons

  • Less long-lived than the MLC (2-bit) SSDs

With top-notch performance and stellar longevity ratings, this drive is as good as it gets when it comes to 2.5-inch SATA SSDs. It's also available with up to 4TB of capacity, which should be enough for even the most demanding users. Pricey, but the best.

Pros

  • Excellent SATA performance
  • Available with up to 4TB of space
  • Uses long-lived 2-bit MLC NAND

Cons

  • Expensive
  • Not availabel in the M.2 form factor

Though there are occasional performance dips (likely while the drive does housekeeping) this SSD turned in some of the best numbers we've seen. Affordable and light, it's a great laptop or PC upgrade.

Pros

  • Good performance
  • Affordable
  • Thin (7mm) and light

Cons

  • Occasional performance dips

This PCIe/NVMe SSD is cheaper than Intel's similar 750, and not that much slower. It also looks good, for gamers showing off their PC's internals.

Pros

  • 2GBps reads, 1GBps writes
  • Sylish heatsink and activity lights

Cons

  • TBW rating of the 1TB model is slightly low

A very good performer, the 2.5-inch Sony SV-GS46 Professional SSD is also warrantied for 10 years (most others top out at 5 years) and is rated for 2.5TBW (TeraBytes Written) for every 1GB of capacity. Reassuring, but the drive also costs twice or more than the average 2.5-inch SSD.

Pros

  • Incredible 10-year warranty and 1,200TBW
  • No performance drop-off when writing large amounts of data

Cons

  • Very expensive

The Intel SSD 660p will shake up the low end of the NVMe market with very good performance at an unprecedented price, even though write speeds can drop precipitously to 100MBps when very large amounts of data are written to the drive, or when it begins to fill up. Note that the 512MB version offers significantly slower performance.

Pros

  • Very good NVMe performance most of the time
  • Absurdly affordable
  • 4-bit QLC NAND promises up to 4TB in future releases

Cons

  • Slows to 100MBps writing during very long transfers

We were ready to love this NVMe SSD because of its superlow price, but while indeed it is near the price of SATA, so is the sustained write speed. That said, in everyday use, you will see that NVMe kick in the pants performance.

Pros

  • Exceptionally affordable for an NVMe SSD
  • Very fast reader

Cons

  • Very slow writer for NVMe
  • Low TBW rating compared to recent competition

Intel's Optane technology shows promise and scales well, but it's four times the price and doesn't offer the capacity of NAND-based solutions. While we rated the 800P at 3 stars, that's with the average user in mind. It would rate higher as a corporate solution, where its marvelous longevity would come into play.

Pros

  • Fast with non-queued small file reads
  • Outstanding longevity

Cons

  • Slow sustained writes for an NVMe drive
  • Four times the cost of the NAND-based competition
