Short answer: match the drive to the fastest port you actually have. On a recent Mac or a PC with USB4 or Thunderbolt, a USB4 drive such as the Corsair EX400U is the one to buy for editing straight off the drive. For backups, sample libraries on an older laptop, or a mixed Mac and PC studio, a 10Gbps drive such as the Samsung T7 Shield runs at full speed everywhere. Skip 20Gbps "Gen 2x2" drives if you work on a Mac.
The speed tiers in plain words
- 10Gbps (USB 3.2 Gen 2): about 1,000MB/s. Every current Mac and most PCs run these at full speed.
- 20Gbps (USB 3.2 Gen 2x2): about 2,000MB/s, but only on a PC port that supports Gen 2x2. Apple silicon Macs connect these at 10Gbps (Apple Community); Wirecutter found the same on a USB4 laptop (Wirecutter). Some Intel Macs are an exception (Eclectic Light).
- USB4 (40Gbps): about 3,000 to 4,000MB/s on USB4 or Thunderbolt ports, which most recent laptops and all Apple silicon Macs have.
- Thunderbolt 5: up to about 6,000MB/s, and only on a Thunderbolt 5 computer.
What creators need from a drive
Video: phone 4K at default settings takes about 190MB a minute, while 4K 10-bit ProRes HDR takes about 6GB a minute; recent Pro iPhones can record ProRes straight to an external SSD (Wirecutter). A 10Gbps drive handles most 4K editing; ProRes, RAW and multicam timelines are where USB4 pays off.
Sample libraries and project files: these load thousands of small files, so random-read speed matters more than the headline number. Wirecutter's tests show USB4 drives well ahead on small files, with the SanDisk Extreme PRO USB4 the exception on small writes (Wirecutter).
Mac and PC in one studio: format the drive as exFAT to read and write it on both. Use APFS for a Mac-only drive or for Time Machine (Apple Disk Utility guide). Formatting erases the drive, so do it before you copy anything.
Prices: Wirecutter reports flash storage prices rose sharply through 2026 and some drives go in and out of stock, so check the current price before you decide between tiers (Wirecutter).
10Gbps drives: full speed on any computer
10Gbps tier: rugged all-rounder
Samsung T7 Shield
Capacity options: 1TB, 2TB, 4TB
Interface: USB 3.2 Gen 2 (10Gbps), USB-C; C-to-C and C-to-A cables in the box
Rated speed: up to 1,050MB/s read, 1,000MB/s write; IP65
Best for: a laptop bag drive that runs at full speed on any Mac or PC
Skip if: you have USB4 or Thunderbolt ports and want three times the speed
Specs from Samsung and its 4TB launch note (three-year warranty). It was Wirecutter's top pick until USB4 drives replaced it, and its photography director keeps 32,000 images on one (Wirecutter). Common complaint: owners on Reddit report the USB-C cable working loose and the drive dropping off mid-copy; a snug or shorter cable usually fixes it (r/techsupport).

SanDisk Extreme Portable SSD
Capacity options: up to 4TB (check the current listing)
Interface: USB 3.2 Gen 2 (10Gbps), USB-C
Rated speed: up to 1,050MB/s read, 1,000MB/s write; IP65, 3-meter drop rating
Best for: field shoots where dust, rain and drops are likely
Skip if: you want the cleanest reliability record in this class
Specs from the SanDisk product page. Praise centers on the tough shell and wide availability. The complaint is serious: in 2023 owners reported sudden failures and lost data on Extreme and Extreme Pro portable drives, a lawsuit followed, Western Digital shipped a firmware update, and some users said problems persisted after it (The Register; Tom's Hardware; TechSpot). If you own one, update its firmware and keep it backed up.

20Gbps tier: fast on the right PC port
Samsung T9
Capacity options: 1TB, 2TB, 4TB
Interface: USB 3.2 Gen 2x2 (20Gbps), USB-C; C-to-C and C-to-A cables
Rated speed: up to 2,000MB/s read, 2,000MB/s write; five-year limited warranty
Best for: Windows desktops with a 20Gbps USB-C port and long 4K timelines
Skip if: you edit on a Mac: it runs at about half speed there
Specs from Samsung. Wirecutter lists it as worth considering for extra space, but on its USB4 laptop the T9 read at about 1,066MB/s, the same as 10Gbps drives, because most laptops and phones lack a Gen 2x2 port (Wirecutter). AnandTech found sustained writes drop once the cache fills and firmware limits heat (AnandTech); Reddit owners describe the controller getting hot on big transfers (r/DataHoarder).

Lexar SL500
Capacity options: 1TB, 2TB, 4TB
Interface: USB 3.2 Gen 2x2 (20Gbps), USB-C; C-to-C cable
Rated speed: up to 2,000MB/s read, 1,800MB/s write
Best for: backing up a laptop and carrying projects for less money
Skip if: you need a USB-A cable in the box or full speed on a Mac
Specs from Lexar. Wirecutter's budget pick: a metal body that helps with heat, a five-year warranty, and faster than average among non-USB4 drives in its tests (Wirecutter). Complaints from the same review: the Gen 2x2 interface is supported by very few laptops and desktops, so most people get 10Gbps speeds, and there is no USB-A cable or adapter.

USB4 tier: fastest for most people
Corsair EX400U
Capacity options: 1TB, 2TB, 4TB
Interface: USB4 (40Gbps), USB-C; falls back to 20Gbps and 10Gbps
Rated speed: up to 4,000MB/s read, 3,600MB/s write; three-year warranty
Best for: editing video straight off the drive on an Apple silicon Mac or USB4 PC, and iPhone recording
Skip if: you shoot outdoors and need a rated rugged drive
Specs from Corsair. Wirecutter's current top pick: about 3,200MB/s in its tests, strong small-file speed, a MagSafe ring for iPhone 15 and later, and an activity light (Wirecutter). Complaints: no USB-A cable, a shorter warranty than SanDisk or Lexar, frequent stock shortages, and a reviewer noted it runs noticeably warm during long writes and has no water or dust rating (The SSD Review).

Check the current price on AmazonUSB4 tier: rugged and fast
SanDisk Extreme PRO with USB4
Capacity options: 2TB, 4TB
Interface: USB4 Gen 3x2 (40Gbps), USB-C; macOS 14 or later
Rated speed: up to 3,800MB/s read, 3,700MB/s write; IP65; five-year limited warranty
Best for: big sequential copies: camera dumps, 4K and 8K files, project archives
Skip if: you run sample libraries or apps from the drive
Specs from SanDisk. It matched the Corsair on large files in Wirecutter's tests, but random writes of small files topped out near 24MB/s against over 110MB/s for the Corsair, and it is much larger (Wirecutter). Tom's Hardware also flags disappointing write speeds (Tom's Hardware).

OWC Envoy Ultra
Capacity options: 2TB, 4TB; an 8TB model was announced in January 2026
Interface: Thunderbolt 5 with a built-in cable; works on Thunderbolt 3 and 4 and USB4 at lower speed
Rated speed: up to 6,000MB/s; OWC lists sustained writes of 1,350MB/s (2TB) and 1,700MB/s (4TB); IP67
Best for: Thunderbolt 5 Macs and PCs editing 8K or multicam footage on the drive
Skip if: your computer has no Thunderbolt 5 port; a USB4 drive gets close for less
Specs from OWC; 8TB news via Newsshooter. TechRadar measured close to 48Gbps and called it the fastest single-drive portable SSD you can buy (TechRadar). The catch is in OWC's own numbers: long writes settle far below the headline speed, and the captive cable cannot be swapped for a longer one.

Which drive should you buy?
- Apple silicon Mac, editing video or running sample libraries from the drive: Corsair EX400U, or the OWC Envoy Ultra on a Thunderbolt 5 Mac.
- Mixed Mac and PC studio, or an older laptop: Samsung T7 Shield.
- Windows desktop with a 20Gbps USB-C port: Samsung T9 or Lexar SL500.
- Outdoor shoots and camera dumps: SanDisk Extreme PRO with USB4, with a second copy elsewhere.

Frequently asked questions
Is a 20Gbps USB 3.2 Gen 2x2 SSD faster on a Mac?+
No. Apple silicon Macs connect Gen 2x2 drives at 10Gbps, so they run at about the same speed as a cheaper 10Gbps drive. On a Mac, buy a 10Gbps drive or a USB4 or Thunderbolt drive.
What format should an external SSD use for both Mac and PC?+
exFAT. Both systems read and write it. Use APFS only for a Mac-only drive or a Time Machine backup.
Do I need USB4 or Thunderbolt for 4K video editing?+
Not for most 4K work: a 10Gbps drive handles it. USB4 or Thunderbolt helps with ProRes, RAW, multicam timelines and very large copies.
Is an external SSD a backup?+
Not on its own. It is one copy in one place. Keep a second copy on another drive and a third copy offsite or in the cloud.
Which external SSD is best for sample libraries?+
One with strong random-read speed on the port you have. Wirecutter's tests put USB4 drives such as the Corsair EX400U ahead on small files; on an older laptop a 10Gbps drive such as the Samsung T7 Shield is fine.
