Fastest Rated Read Speed1 of 5
LaCie Rugged SSD4 1TB
LaCie's Rugged SSD4 uses a 40Gbps USB connection and offers 4,000MB/s reads and 3,800MB/s writes, the fastest figures here.
Best for
- Buyers who put rated read speed first.
Skip if
- Skip it if capacity matters most to you; the T9 2TB offers 2TB.
Why we like it
It is the only 1TB drive in this guide, and it needs a USB4 or Thunderbolt port to reach those speeds. It reads at up to 4,000MB/s over USB 40Gbps and Thunderbolt, and it is IP54-rated with 3-metre drop and 1-ton crush resistance. It suits fieldwork with large video files.
Its 1TB capacity is the smallest in this group; the T9 2TB leads at 2TB. Nothing else here matches its 4,000MB/s rated read speed; the X10 2TB comes closest at 2,100MB/s. It also comes with compatibility with Thunderbolt 3, 4 and 5 as well as 5-20Gbps USB and a three-year warranty with Rescue data recovery. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the T9 2TB and the rest.

Also Consider2 of 5
Samsung T9 Portable SSD 2TB

- All 5, from the Rugged SSD4 to the T7 2TB, state drive type, capacity and rated read speed.
- Where the specs have gaps
- The T9 2TB gives no durability claim.
- Price range
