Maybe your gaming laptop doesn’t have enough storage. Or maybe you simply want to render your game library portable between systems. Rather than upgrade your internal storage — add a speedy external SSD. Not only will you have a lot more fast storage for your games, you can use it on any system you wish.
But choosing the external SSD that’s right for your needs means sorting through a dizzying array of protocol and speed options. Making a poor choice might leave you feeling hard done by, either monetarily or performance-wise. Luckily for you, we’ve tested multitudes of the wee beasties and can offer recommendations guaranteed to improve your gaming experience.
Below we offer recommendations from 80Gbps down to 10Gbps; scroll below those to learn more about our evaluation process and what to look for when buying an external SSD for gaming.
Note that SSD prices have risen considerably since our original reviews thanks to the AI / data center gold rush, and the recommendations below reflect that new reality. The older, linked reviews may not. We’ve also added a couple of enclosures to which you can add your own NVMe SSD, as the availability of many pre-populated SSDs is currently scattershot. Furthermore, an enclosure / DIY option is a way to save money in these time of inflated prices.
Why you should trust PCWorld for external drive reviews and buying advice: PCWorld has been putting computer hardware through its paces for decades. Our external drive evaluations are thorough and rigorous, testing the limits of every product — from performance benchmarks to the practicalities of daily use. As consumers ourselves, we know what makes a product exceptional, or not. For more about our testing process, scroll to the bottom of this article.
LaCie Rugged SSD Pro5 – Best 80Gbps external SSD for gaming
Pros
- Supports Thunderbolt 5 and USB4
- Impressive 80Gbps performance for creative pros
- Rugged IP68-rated design
- Longer than average five-year warranty
Cons
- Expensive
- Requires 80Gbps Thunderbolt 5/USB4 port for full performance
Who should buy the LaCie Rugged SSD Pro5?
Anyone looking for top performance from an external SSD and who has the somewhat rare 80Gbps port to handle it, should shop the LaCie Rugged SSD Pro5. It’s not the fastest 80Gbps SSD I’ve tested, but it was close. Better, it’s available most of the time and its price hadn’t gone through the roof when I last checked.
LaCie Rugged SSD Pro5: Further considerations
The silicone-wrapped Rugged SSD Pro5 is beefed up to the tune of IP68 to ward off dust and liquids. It also features a full five-year warranty — two years longer than the norm for external SSDs. And while SSD components all come from the same sources, the LaCie (Seagate owned) name means something in the industry.
Note that this drive was reviewed for sister publication Macworld, but by this same author and run through the same battery of tests I use for my PCWorld reviews.
Adata SE920 – Best 40Gbps USB4 external SSD for gaming
Pros
- Fastest pre-populated 40Gbps SSD we’ve tested
- Fan-cooled enclosure
- Also fast on the Mac
Cons
- Pricier than USB 3.2×2 (20Gbps)
Who should buy the Adata SE920?
For those who still want stellar sustained throughput, but for less moolah than an 80Gbps SSD, the 40Gbps SE920 will get the job done and then some. Note, a 40Gbps USB4 external SSD isn’t for everyone. Your PC needs to support the USB4 or the Thunderbolt 3/4/5 spec in order to take advantage — and while cheaper than 80Gbps, it’s still not cheap.
If you’re equipped to enter the club, the Adata SE920 EX will reward you with nearly 4GBps transfers, and at a slightly more affordable price than our previous pick for USB4, the OWC Express 1M2 — we’re talking $280 for a 1TB Adata SE920 versus $300 for the 1TB OWC drive. If you want a lot of capacity, the Adata SE920 EX ships with up to 4TB, though like all such-capacity SSDs, it’s currently in short supply and has become very expensive.
Adata SE920: Further considerations
In almost every benchmark, the SE920 EX beat the OWC Express 1M2, albeit by very small margins. It also comes with a nifty built-in fan, which is activated by sliding open the enclosure. This kept my drive noticeably free of heat during benchmark tests.
The SE920 EX is also quite portable at around 4.1 inches long by 2.5-inches wide by 0.6-inches thick, and weighing 7 ounces — another advantage it has over the bulkier OWC Express 1M2 and others.

TerraMaster D1 SSD Plus – Best 40Gbps external SSD enclosure for gaming
Pros
- Second-fastest USB4 enclosure to date
- Solid, thermally excellent design
- Good-looking
Cons
- Bulky
Who should buy the TerraMaster D1 SSD Plus?
With the price of pre-populated 40Gbps SSDs rising due to the AI / data center memory arms race, buying a $110 (currently $70 on sale) 40Gbps enclosure such as the TerraMaster’s D1 SSD Plus, and then adding your own NVMe SSD is quite likely your most affordable external high-speed SSD option.
TerraMaster D1 SSD Plus: Further considerations
The TerraMaster D1 SSD Plus is bulky, and the style may not be everyone’s cup of tea, but the overtly-finned aluminum enclosure sheds the heat inherent with faster 40Gbps SSDs extremely well.
When you populate the D1 SSD Plus, don’t overbuy with a PCIe 5.0 NVMe SSD, unless you want said SSD for use in something faster in the future. An affordable PCIe 4.0 model provides as much speed as the 40Gbps bus can handle. Note that TerraMaster also makes an 80Gbps enclosure, the D1 SSD Pro.

PNY RP60 – Best 20Gbps external SSD for gaming
Pros
- Handsome, IP65-rated design (dust proof, water resistant)
- Good 20Gbps performance
- Nice flat Type-C USB ribbon cable
Cons
- USB port plug tether is difficult to reinsert.
Who should buy the PNY RP60?
If you tend to take your gaming drive everywhere, and/or you’re not the most careful person with hardware, a ruggedized external SSD is a practical way to ward off accidental damage.
The PNY RP60 offers more than just a rugged IP65-rated exterior that protects against dust and water droplets. It’s handsome and lightweight to boot, as well as an admirable performer, even besting one of the fastest 20Gbps drives I’ve tested — the Crucial X10 Pro — in a couple of our tests.
PNY60: Further considerations
A 20Gbps SSD is the sweet spot in the price/performance ratio for external SSDs. The only issue is that the USB 3.2×2 drives function at only 10Gbps or slower unless attached to a dedicated 20Gbps port. That applies to most USB4 and Thunderbolt ports as well.
The RP60 is competitively priced at $130 and $270 for 1TB and 2TB, respectively. Note that these prices are significantly higher than when I first reviewed the RP60 due to the global NAND shortage.

Asus TUF Gaming A2 – Best 20Gbps external SSD enclosure for gaming
Pros
- Very fast performer
- Military-esque styling
- Super-rugged IP68 rated
- Affordable
Cons
- You need to provide the NVMe SSD
- Requires a USB 3.2×2 port for 20Gbps performance
Who should buy the Asus TUF Gaming A2?
Many gamers build their own gaming rig, so why shouldn’t they roll their own external SSD with an affordable enclosure such as the $60 TUF Gaming A2? With the price of pre-populated external SSDs currently reaching for the stratosphere, it’s an especially attractive proposition for 2026.
The TUF Gaming A2 is styled to appeal to gamers, especially fans of first-person, military-style shooters. It’s built like a tank, carries an IP68 rating, and is easy to open for installing your NVMe SSD.
Asus TUF Gaming A2: Further considerations
The TUF Gaming A2 allows you to leverage older NVMe SSDs. Even a PCIe 3.0 SSD is fast enough for the 20Gbps bus, if you find a deal. With those going the way of the Dodo, however, an affordable PCIe 4.0 model will do just fine.

Corsair EX300U – Best 10Gbps external SSD for gaming
Pros
- Fastest 10Gbps SSD we’ve tested
- Small profile
- Magnetic attachement to metal surfaces
Cons
- Almost as pricey as 20Gbps SSDs currently
Who should buy the Corsair EX300U?
For those looking for an SSD that won’t break the bank, but is still “fast enough,” the EX300U is an appealing little magnetic square of a drive. That said, $130 and $245 for 2TB is almost as pricey as the 20Gbps PNY RP60 listed above. Formerly, the drive was $100 and $180 respectively at those two capacities.
Scant savings aside, the EX300U is the fastest 10Gbps SSD I’ve tested to date, besting the Teamgroup X2 Max listed below by a small margin. And unlike the latter, you can stick it to a metal object like a PC case via the circular magnet on the back. Note that aluminum is not particularly magnetic, so this doesn’t work with most Macs.
Corsair EX300U: Further considerations
The warranty on the EX300U is three years, which is the usual for external SSDs, but the 250TBW (terabytes that can be written) per terabyte of capacity is a little stingy. At least Corsair provides a TBW rating — most vendors don’t for external SSDs.
Still, the odds of anyone exceeding that TBW limit is rather low. Most of the time games are reading data, not writing it.

Teamgroup X2 Max — Best 10Gbps thumb drive SSD for gaming
Pros
- Svelte thumb drive form factor
- Fastest 10Gbps SSD we’ve tested
- Dual Type-A/Type-C connectors
Cons
- End caps aren’t captive
Who should buy the Teamgroup X2 Max?
For those who want both fast 10Gbps performance, plus the super convenience of the thumb drive form factor and both Type-A and Type-C connectivity, it doesn’t get any better than the X2 Max. In fact, it’s the second-fastest 10Gbps SSD of any type that I’ve tested. Right behind the Corsair EX300U shown above.
While it may not be sexy-looking in the gaming sense, pulling this out of your pocket when you sit down to game is the ultimate sandbag move. Let them laugh, they’ll never see you coming.
Having both Type-A and Type-C connectors on board means never having to worry about what type of computer you’ll be using the X2 Max on, though having a thumb drive attached to your laptop can be a bit awkward if you’re lounging on the couch, etc.
Teamgroup X2 Max: Further considerations
While some gamers might scoff at “only” 10Gbps, that’s still plenty fast enough for loading games — and seek times are roughly the same as 80/40/20Gbps SSDs. Where you’ll lose out a bit compared to those faster models is in the time it takes saving games in the first place.
Note that the 2TB X2 Max was on target for a 10Gbps SSD writing our 450GB file, never slowing appreciably or tragically as some do. The 1TB might not do quite as well.
The current pricing of $210 for the 2TB model means you should weight this option against faster options for a little more cash, and/or creating your own external SSD using the enclosures listed above. A roll-your-own model, however, will never be this portable.

Other notable external SSDs for gaming:
The MSI DataMag 40Gbps is not the fastest USB4 drive, but it’s got magnetic mounting; and the 20Gbps Teamgroup PD20 is handsome, tough, and decently fast.
The Crucial X10 is a tiny, weatherproofed drive that can hold up to 8TB of storage. There’s also a lot to like about the Sandisk Extreme Pro SSD with USB4 — 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, but can sometimes be found for less expensive than the competition. The Seagate Game Drive SSD is targeted at PS4/PS5 owners, and this 10Gbps SSD is very fast for its class as well as attractively styled, complete with a Playstation logo, though 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.
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 Crucial 64GB DDR5 5600MHz modules (128GB of memory total).
Both 20Gbps USB and Thunderbolt 5 are integrated into the motherboard and Intel CPU/GPU graphics are used. Internal PCIe 5.0 SSDs involved in testing are mounted in an Asus Hyper M.2 x16 Gen5 adapter card sitting in a PCIe 5.0 slot.
We run the CrystalDiskMark 8.04 (and 9), AS SSD 2, and ATTO 4 synthetic benchmarks (to keep article length down, we report only the first) to find the storage device’s potential performance. Then we run a series of 48GB transfer and 450GB write tests using Windows Explorer drag and drop to show what users will see during routine copy operations, as well as the far speedier FastCopy run as administrator to show what’s possible.
A 25GBps two-SSD RAID 0 array on the aforementioned Asus Hyper M.2 x16 Gen5 is used as the second drive in our transfer tests. Formerly the 48GB tests were done with a RAM disk serving that purpose.
Each test is performed on a 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 issue has abated somewhat with the current crop of SSDs utilizing more mature controllers and 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?
At 80Gbps, the LaCie Rugged SSD Pro5 is our choice for absolute best performance. If speed is important, but you want to save a bit of coin, then the best 40Gbps external drive is the Adata SE920. For still-great 20Gbps performance, and a significant cost savings, consider the PNY RP60 and Crucial X10 Pro. Note that the Teamgroup X2 Max still offers good 10Gbps in a super-small form factor.
What are the speeds of the various external interfaces and which one do you want?
In descending order of performance the current external interfaces are: 80Gbps Thunderbolt 5/USB4, 40Gbps USB4/Thunderbolt 3 and 4, 20Gbps USB 3.2×2 (dedicated port required or it’s 10Gbps), 10GBps USB 3.2, then 5Gbps USB 3.x. For optimal gaming performance, we recommend 20Gbps or higher, though you can easily make do with 10Gbps.
Note that currently, the real-world difference in performance between 40Gbps and 80Gbps is minimal. Also, the increase in power draw and heat produced as you climb the performance ladder from 10Gbps to 80Gbps is noticeable.
Note that you’ll occasionally see mentions of 120Gbps Thunderbolt 5. 120Gbps is only available for downstream video, not storage or other applications. 80Gbps is the current top of the line.
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 give up the ghost. 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. There were also instances in the ancient past of static electricity bricking Type-A connected SSDs upon insertion.
Why does Windows say my external drive has less capacity 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 2 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 2 terabytes, or 2TB. Vendors use this system as consumers are far more familiar with base 10 than binary.
However, Windows uses the newer International Electrotechnical Commission (IEC) binary multiples such as 2^10 (Kibibyte/KiB), 2^20 (Mebibyte/MiB), 2^30 (Gibibyte/Gib), etc. Binary multiples are larger than their decimal near-equivalents (one KiB is 1,024 bytes, one MiB is 1,048,576 bytes) so when Windows divides the total bytes by the IEC values you get something like 1.8TiB for a 2TB drive. Alas, Windows labels this as 1.8TB rather than 1.8TiB, 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 actually 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. As with all such things, it’s a financial risk formula calculated by the company. In this case based on expected NAND longevity and price. As is the TBW rating. 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.
Exceeding a SSD’s rating does not affect the data stored on it. You can still read that data, you just can’t write more of it to the drive.
Should you build your own external SSD with an enclosure and an NVMe SSD?
Due to the current high price of NAND, buying an enclosure and populating it with an NVMe SSD is a more enticing proposition than ever before, and it has always appealed to PC builders. Note that even a PCIe 3.0 NVMe SSD will give you good performance in up to 20Gbps enclosures, though you’ll need at least a PCIe 4.0 model to get the most out of an 40/80Gbps enclosure.
