Best External SSDs for Mac in 2026

How We Chose the Best External SSDs for Mac

Because modern Macs cannot have their internal storage upgraded, the external SSD you plug into a USB-C port becomes the primary way to add space, and choosing well matters. We built this list around the realities of Mac use: every drive here connects over USB-C, works with macOS without special drivers, and suits the two things Mac owners most often need extra storage for, backing up their machine and offloading large photo and video files. From there we separated the field by what each drive does best, from everyday backups to high-speed editing.

The specifications we weighted most heavily were interface generation and real transfer speed, since a USB 3.2 Gen 2 drive and a Gen 2x2 drive feel very different in heavy use, followed by capacity and price per gigabyte. We then looked at durability, because a portable drive that travels benefits from drop and water resistance, and at practical extras like bundled cables, encryption and backup software. Owner ratings kept the picks honest, and we deliberately mixed affordable everyday drives with premium creator SSDs so there is a right answer whether you want a cheap backup or a drive to edit 6K footage on.

Understanding External SSD Speeds on a Mac

The most confusing part of buying an external SSD is speed, because the headline number only tells half the story. Two interface tiers dominate this list. The first, USB 3.2 Gen 2, tops out around 1,050 MB/s and covers most drives here, including the Samsung T7, SanDisk Extreme and Crucial X9. That speed is plenty for Time Machine backups, copying photo libraries and light editing, and it runs at full pace on essentially any modern Mac's USB-C or Thunderbolt port.

The second tier, USB 3.2 Gen 2x2, roughly doubles that to around 2,000 MB/s, and it is where the Samsung T9 and Crucial X10 sit. This extra speed genuinely helps when you edit 4K or 6K video directly off the drive, since the timeline scrubs and exports more smoothly. The important caveat is that your Mac needs a port supporting the 20Gbps 2x2 standard to unlock it; on a port that does not, these drives fall back to around 1,000 MB/s. Before paying the premium for a 2x2 drive, confirm your Mac can actually use it, otherwise a good Gen 2 drive is the smarter buy.

Capacity and Value for Mac Users

How much space you need depends on the job. For a Time Machine backup, a sensible rule is a drive roughly twice the size of your Mac's internal storage, which is why 2TB models such as the Samsung T7 2TB, SanDisk Extreme 2TB and Crucial X9 make excellent backup targets. They give macOS room to keep multiple versions of your files, and because SSDs are so much faster than old mechanical drives, those backups finish quickly and quietly in the background.

For carrying working files, size to your media. A photographer shuttling RAW libraries or a videographer with 4K footage will fill 1TB fast, so a 2TB drive earns its keep, while someone using the drive as an occasional backup or scratch disk can save money with the SSK 500GB or a 1TB option like the SanDisk Extreme 1TB. As always, compare cost per gigabyte rather than sticker price, since a well-priced 2TB drive often works out cheaper per gig and spares you a second purchase when your files inevitably grow.

Best External SSDs for Backups

Backing up a Mac is arguably the most valuable thing an external SSD does, and the ideal backup drive is roomy, reliable and fast enough to make Time Machine painless. The Samsung T7 2TB is our favourite here, combining generous space, proven Samsung reliability and 1,050 MB/s speeds that let full backups complete in a fraction of the time an old hard drive would take. Format it to APFS in Disk Utility, point Time Machine at it, and it quietly protects your Mac from then on.

For a backup drive that also travels, the SanDisk Extreme 2TB adds IP65 weatherproofing and drop protection, so it survives being tossed in a bag between home and office. The Crucial X9 2TB is another strong option thanks to its bundled Acronis True Image software, which offers an alternative to Time Machine for disk imaging. Whichever you choose, the key is capacity headroom, so pick a drive comfortably larger than the data you are protecting, and let it run automatically rather than backing up by hand.

Best External SSDs for Video and Photo Editing

Creators put the heaviest demands on external storage, because editing directly off a drive means the drive's speed becomes your workflow's speed. The Crucial X10 2TB leads here with up to 2,100 MB/s, the fastest on this list, plus rugged IP65 protection for location work, making 4K and 6K timelines feel responsive on a capable Mac. The Samsung T9 is close behind at up to 2,000 MB/s, and its Dynamic Thermal Guard keeps performance steady through long exports rather than throttling partway through a render.

Both fast drives depend on your Mac having a 20Gbps 2x2 port to hit those speeds, so verify that before buying. If your Mac only has slower ports, or your projects are less demanding, the Samsung T7 and its 2TB version still handle photo libraries and lighter video edits comfortably at 1,050 MB/s. The extra headroom of a 2x2 drive is a real benefit for professional video, but it is wasted money if your machine cannot feed it, so match the drive to your actual editing needs and hardware.

Durability, Security and Portability

A drive that leaves your desk lives a harder life, and the right protection prevents lost data. The SanDisk Extreme and Crucial X10 both carry IP65 ratings against dust and water plus multi-metre drop resistance, which genuinely matters on shoots, commutes and trips where a drive gets knocked around. The Crucial X9's IP55 rating is a step down but still useful, while non-rugged drives like the Samsung T7 trade weatherproofing for a slimmer, cheaper package best suited to gentler, desk-bound use.

Security deserves thought if you carry sensitive work. The SanDisk Extreme includes 256-bit AES hardware encryption to lock files behind a password, and Samsung's Magician software brings encryption and drive-health monitoring to the T7 and T9. Portability extras add convenience too: the SSK drives bundle both USB-C and USB-A cables and work with recent iPhone Pro models, handy in a mixed Apple household, while the SanDisk Extreme's carabiner loop clips it to a bag. Match the toughness and security to how much the drive travels, and you avoid both over-paying and under-protecting.

A Closer Look at the Top Picks

The Samsung T7 1TB earns the overall top spot because it strikes the best balance for the widest range of Mac users: fast enough for almost everything, compact enough to forget it is in your pocket, and priced sensibly. Its 2TB version is the natural step up for anyone with a large library or a Time Machine backup to run, keeping the same speed and reliability with room to spare.

For buyers who want ruggedness and value, the SanDisk Extreme in 2TB and 1TB is the standout, wrapping fast, encrypted storage in a weatherproof, drop-resistant shell. Creators editing off the drive should look to the Crucial X10 for its class-leading 2,100 MB/s speed or the Samsung T9 for a fast, cool-running alternative. The Crucial X9 is the easygoing everyday drive with bundled backup software, and the SSK 1TB and 500GB cover the budget end while doubling as iPhone companions.

Final Recommendation

For most Mac owners, the Samsung T7 is the best external SSD in 2026, offering the ideal blend of USB-C speed, pocketable size and value, with the 2TB version ready for larger libraries and backups. If your drive travels, the rugged SanDisk Extreme is the smart choice, and if you edit video off the drive, the 2,100 MB/s Crucial X10 or the fast Samsung T9 are worth the premium on a 2x2-capable Mac. The Crucial X9 suits casual users wanting bundled backup software, and the SSK drives cover tight budgets and iPhone offloading. Match the speed, capacity and toughness to how you work, and any pick here will serve your Mac well for years.
