The competition is very close in the top tier of 20Gbps external drives, with the big-name contenders trading wins up and down the benchmark charts. But a winner is a winner, and in the end, the Lexar overtook our previous champ, Crucial’s X10 Pro, even if only by a hair.
The upshot is that you can expect excellent performance from the Lexar SL600. It also comes in a uniquely shaped form factor, complete with an opening to accommodate a lanyard, for easy toting. Gamers might appreciate that you can even add some bling by opting for the SL660 variant, which features RGB lighting within its miniature handle. The drive comes with the standard five-year warranty.
When performance is this closely matched among products, the determining factor should be price. And here, too, the SL600 is neck-and-neck with the Crucial X10 Pro, and priced slightly to significantly cheaper than some of its competitors, at least as of this writing — particularly at the 2TB level.

If you’re after a very small SSD that you can easily fit into a pocket, the Sabrent Rocket Nano V2 is that. This USB 3.2×2 20Gbps drive measures a petite 2.73 inches long, 1.16-inches wide, and 0.44-inches thick. It weighs a dainty 1.7 ounces.
Of course, you’ll probably want to slide on its included shock-absorbing silicone jacket (shown in picture), which will add .06 inches to all its dimensions, while giving it a badass look.
But looks aside, the Nano V2 is a solid performer. It wasn’t quite at the same level as our top picks in everything, but it traded wins and losses within the pack. For instance it was second only to the Crucial X10 Pro in our 450GB write test. And it took the top spot in CrystalDiskMark 8’s random writes, and was very competitive in random reads.
This wee drive also comes in up to 4TB capacities, making it an all-around good choice if you’re looking to get a lot of storage and performance in a tiny package. We’re also fond of its five-year warranty and the nifty metal box it comes in, which can be repurposed for other uses.

A USB4 external SSD isn’t for everyone. Not only does your PC need to support the spec in order to take advantage of the 40Gbps transfers, but you’ll also need to be willing to pay a premium for the privilege.
If you’re ready to enter the club, however, the Adata SE920 EX will reward you with the fastest USB4 performance that we’ve experienced, and at a much more affordable price than our previous pick for USB4, the OWC Express 1M2 — we’re talking $170 for a 1TB Adata SE920 versus $230 for the OWC drive. And if you want a lot of capacity, the Adata SE920 EX comes with up to 4TB, for a reasonable $418 (compared to OWC’s $550).
In almost every benchmark, the SE920 EX beat the OWC Express 1M2 at 40Gbps performance, albeit by small margins. It also comes with a nifty built-in fan, which is activated by sliding open the enclosure. This kept our drive noticeably free of heat during our benchmark tests.
The SE920 EX is also quite portable at 4.13 inches long by 2.52-inches wide by 0.62-inches thick, and weighing 7 ounces — another advantage it has over the bulkier OWC Express 1M2.
In the end, the choice for a USB 4 external SSD is clear.

The LaCie Rugged SSD4 is the top choice for anyone looking to leverage the best performance from their USB4 or Thunderbolt 3 (or greater) ports.
In our benchmarks, the Rugged SSD4 proved to be the speediest 40Gbps USB4 overall that we’ve tested, albeit by a small margin. Even when tasking the drive to write several 950GB files consecutively, where you expect to see a drive slow down as its cache fills, the SSD4 never dropped below 1.65GBps — something videographers should take note of.
Its silicone jacket is IP54 rated for protection against dust and water spray, making it a good choice for anyone who needs storage out in the field. Its bright orange color makes it easy to find in a crowded bag or atop a cluttered workspace.
And while the SSD4 is not exactly cheap, it’s competitively priced.

Other notable external SSDs for gaming:
The 20Gbps Teamgroup PD20 is handsome, tough, and decently fast; the TerraMaster D1 SSD Plus 40Gbps drive enclosure, populated with the NVMe drives of your choosing, is an interesting proposition, as is the Asus TUF Gaming A2 enclosure, which is also rugged; the Crucial X10 is a tiny, weatherproofed drive that can hold up to 8TB of storage in a small form-factor; there’s a lot to like about the Sandisk Extreme Pro SSD with USB4 such as its handsome design and relative affordability, but connection issues and comparably lackluster 40Gbps performance left us unamazed; the Addlink P21 has a compelling combination of good performance and a striking design; while the Corsair EX400U is on the slow side for a USB4 external SSD, it’s also less expensive than the competition; the Seagate Game Drive SSD is targeted at PS4/PS5 owners, and the 10Gbps SSD is very fast for its class and attractively styled, complete with a Playstation logo, but it’s relatively pricey; the Lexar Armor 700 is a 20Gbps drive that can withstand some abuse — perfect for the gamer on the go, or the accident-prone; the Adata SD810 is a solid 20Gbps drive, save for writing large amounts of data, where it slows down. That being said, the 4TB capacity is a particularly good value at just $300.
How PCWorld tests external drives
Drive tests currently utilize Windows 11 24H2, 64-bit running off of a PCIe 4.0 Samsung 990 Pro in an Asus Z890-Creator WiFi (PCIe 4.0/5.0) motherboard. The CPU is a Core Ultra i5 225 feeding/fed by two Kingston Fury 32GB DDR5 4,800MHz modules (64GB of memory total). Both 20Gbps USB and Thunderbolt 5 are integrated and Intel CPU/GPU graphics are used. SSDs involved in the test are mounted in either a HighPoint 7604A 16x 4-slot PCIe 5.0 RAID adapter card or a single-slot Asus ROG M.2 PCIe 5.0 adapter.
We run the CrystalDiskMark 8, AS SSD 2, and ATTO 4 synthetic benchmarks to find the storage device’s potential performance, then a series of 48GB and 450GB transfers tests using Windows Explorer drag-and-drop to show what you’ll see under Window, as well as the far faster FastCopy to show what’s possible. A two-drive 25GBps RAID 0 array on the HighPoint 7604A 16x PCIe 5.0 adapter card is used as the secondary source/destination.
Each test is performed on an NTFS-formatted and newly TRIM’d drive so the results are optimal. Note that in normal use, as a drive fills up, performance may decrease due to less NAND for secondary caching, as well as other factors. This can be less of a factor with the current crop of SSDs with far faster late-generation NAND.
Caveat: The performance numbers shown apply only to the drive we were shipped and to the capacity tested. SSD performance can and will vary by capacity due to more or fewer chips to shotgun reads/writes across and the amount of NAND available for secondary caching. Vendors also occasionally swap components. If you ever notice a large discrepancy between the performance you experience and that which we report, by all means, let us know.
Note also that some of the SSDs in this roundup were tested using other equipment and methodologies which you can read about in the standalone reviews.

FAQ
What is the best external SSD for gaming?
Gamers have a lot of excellent external SSDs to choose from. If speed is important, the best 40Gbps external drive is the Adata SE920 at 40Gbps; for 20Gbps performance, and a significant cost savings, consider the Lexar SL600 and Crucial X10 Pro.
What’s the fastest external interface?
The fastest PC external interfaces are as follows, in descending order: 80Gbps Thunderbolt 5, 40Gbps USB4/Thunderbolt 3 and 4, 20Gbps USB 3.2×2, 10GBps USB 3.2, then 5Gbps USB 3.x.
What causes an external SSD to fail?
While mechanical hard drives are much more prone to failure than SSDs, it is still possible for an SSD to fail. Generally it’s the result of a controller failure, although that’s an increasingly rare occurrence; it’s also a relatively easy fix/reset for someone who knows the SSD’s internals such as a recovery service. SSDs will also eventually wear out, though this only precludes further writing to the unit. You can still read what’s on the drive, so it’s not the disaster a HDD failure can be.
Why does Windows say my external drive is smaller than specified?
This discrepancy is due to the difference between the binary and decimal number systems, their nomenclatures, and a Microsoft miscue. Your 2TB drive indeed has two trillion bytes of storage, and if you look at the byte count that Windows displays in a drive’s properties dialog, this should be what you see. This, in the International System of Units (SI/decimal), is two terabytes, or 2TB. This is the standard language vendors use as consumers are far more familiar with base 10.
However, Windows uses the newer International Electrotechnical Commission (IEC) binary multiples 2^10 (Kibibyte/KiB), 2^20 (Mebibyte/MiB), 2^30 (Gibibyte/Gib). Binary multiples are larger numbers (one KiB is 1,024) so when Windows divides the total bytes by the IEC system, the you get something like 1.8TiB for a 2TB drive. Alas, Windows labels this as 1.8TB, misleading the user.
Other reasons you might not see as much available storage in the properties tab are formatting or partitioning. The file system uses some storage for file location and size info, etc. Also, some drives come with a small partition containing software so the main partition will be smaller than the drive’s total capacity.
How long will my external SSD last?
SSDs don’t wear out or break mechanically like a hard drive, but their cells can only be written to so many times. SSDs generally have a TBW (terabytes that may be written) rating, but this is rarely provided by vendors for external SSDs. Hint: They may not use the same SSD inside throughout the product lifespan.
Most internal M.2 NVMe TLC SSDs are rated for around 600TBW per terabyte, and QLC types for around 200TBW, though the type of NAND in use is also rarely provided by vendors. That’s a lot of data, and a lot of SSDs are rated well below what they might achieve. You can guesstimate by using a utility to see how much data you write to an SSD a day and then doing the math.
External SSD warranties are generally between three and five years, but as with all such things, it’s a financial risk calculation for the company. As is the TBW. Our best guess based on experience is perhaps a decade. However, certain models have had issues long before that — generally due to a flaw or failure in the bridge chip or controller.
