Best External SSDs 2026

External SSDs have gotten absurdly fast. The top drives now push over 4,000 MB/s — faster than most internal NVMe drives from a few years ago. Even budget options crack 1,000 MB/s without breaking a sweat. If you're still using a spinning hard drive for backups, you're leaving speed on the table.

I tested a dozen external SSDs over the past month, running real-world file transfers (not just synthetic benchmarks) with video files, game folders, and photo libraries. Here's what held up.

Quick comparison

Samsung T9

The Samsung T9 is the external SSD I'd recommend to almost anyone. Read speeds consistently hit the advertised 2,000 MB/s mark in our testing — transferring a 50GB video project took about 30 seconds. Write speeds hold steady too, even when dumping 200GB+ of data in one go. Some cheaper drives slow down dramatically during sustained writes as their cache fills up; the T9 doesn't.

Build quality is solid. The rubberized outer shell survived a drop from my desk onto hardwood without any issues, and IP65 means you don't need to panic if it gets caught in the rain.

One thing to check: you need a USB 3.2 Gen 2x2 port on your computer to get full speed. Most modern laptops have at least one, but if your machine only has USB 3.0, you'll be capped around 450 MB/s. Still fast, but not what you're paying for.

SanDisk Extreme Pro V2

SanDisk's Extreme Pro V2 runs neck-and-neck with the Samsung T9 in read performance and costs $10 less. The aluminum body gives it a premium feel and doubles as a heatsink — it gets warm during big transfers but never throttled in my testing.

Write speeds are where it falls slightly behind. On a sustained 150GB write, the SanDisk averaged about 1,700 MB/s compared to the T9's 1,900 MB/s. You won't notice this in everyday use, but if you regularly move massive files, the Samsung has the edge.

The built-in carabiner loop is handy if you toss the drive in a bag regularly. I wouldn't trust it to hold the drive off a cliff, but for clipping to a backpack strap or camera bag, it works.

WD Black P40 Game Drive

The P40 is WD's play for the gaming crowd, complete with customizable RGB lighting along the edge. Whether that's a pro or con depends entirely on your personality. Performance-wise, it advertises 2,000 MB/s but most hosts cap out at 1,050 MB/s via USB 3.2 Gen 2 — the rated speed requires Gen 2x2, which is still rare.

For console gamers, this drive is great for storing PS5 games (though you'll still need to transfer them to internal storage to play). On PC, it works as a fast game library drive. Loading Baldur's Gate 3 from the P40 was maybe two seconds slower than from my internal NVMe.

At $100 for 1TB, it's reasonably priced. Just know that you're partly paying for the brand and the RGB.

Samsung T7 Shield

The T7 Shield won't blow you away with speed numbers, but at $80 for 1TB, it's the value play. Read and write speeds hover around 1,000 MB/s in real-world use, which is plenty fast for photo libraries, document backups, and general file shuttling.

Samsung's been making variations of the T7 for years now, and the Shield variant adds a rubber bumper and IP65 protection. I've used one for over a year as my travel backup drive, and it's been completely reliable. It lives in my camera bag, gets tossed around, and has never lost data.

If you don't need 2,000+ MB/s speeds, this is the smart buy.

Crucial X10 Pro

Crucial's X10 Pro is the dark horse of this list. At $140 for 2TB with speeds up to 2,100 MB/s, the price-to-performance ratio is the best here. Read speeds consistently hit those numbers in testing — slightly faster than both the Samsung T9 and SanDisk Extreme Pro.

The catch is thermal management. The all-aluminum body looks sleek but doesn't insulate your fingers from the heat during big transfers. After copying 100GB, the drive was uncomfortably warm to hold. It never throttled in my tests, but I wouldn't want to use it on a hot day.

Write performance was a little inconsistent. Most transfers hit 1,800-2,000 MB/s, but I saw occasional dips to 1,400 MB/s during very large (300GB+) sustained writes. For most people this won't matter, but video professionals doing massive offloads should test this themselves.

USB 3.2 Gen 2 vs Gen 2x2 vs USB4: what actually matters

Most of the confusion around external SSD speeds comes from USB naming. Here's the quick version:

• USB 3.2 Gen 2 — Up to 10 Gbps (roughly 1,050 MB/s real-world). This is what most laptops have.
• USB 3.2 Gen 2x2 — Up to 20 Gbps (roughly 2,000 MB/s). Less common but growing.
• USB4 / Thunderbolt 4 — Up to 40 Gbps. More than any current portable SSD can saturate.

If your drive is rated for 2,000 MB/s but your laptop only has Gen 2 ports, you'll max out around 1,050 MB/s. The drive still works, just slower. Check your laptop's specs before buying the fastest (and most expensive) option.

What I'd buy

For most people: the Samsung T7 Shield at $80. It's fast enough, tough enough, and cheap enough. If you need maximum speed for video editing or moving huge files, the Samsung T9 at $160 is the safest bet — consistent performance, proven reliability, and a solid warranty.
