Five external drives compared, from the X9 1TB to the Rugged SSD4, with the trade-offs of each named.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
Rugged portable SSDs add drop, dust or water ratings for field work. Every pick has a ruggedness or IP rating, ordered by read speed.
Our comparison rests on published figures for drive type, capacity (as reviewed) and max read speed; where a maker leaves a figure out, we say so, and no figure here comes from our own testing.

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 price comes first: the X9 1TB cost less when we checked.
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.
On rated read speed it leads this guide at 4,000MB/s, ahead of the X10 Pro (2,100MB/s). You also get 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 SanDisk Extreme 2000 and the rest.

How We Chose These Rugged Portable SSDs
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

A small M.2 SSD next to an external drive enclosure Where your budget lands
$150 to $250 buys the X9 1TB, the X10 Pro and the T7 1TB; $250 to $500 buys the SanDisk Extreme 2000 and the Rugged SSD4 at our last check.
Match the pick to your priority
Buyers who put rated read speed first: the Rugged SSD4. Buyers who would rather put the savings elsewhere than into the X10 Pro: the X9 1TB.
An M.2 2280 SSD held in a hand Match the port
A 1,050MB/s SSD needs USB 3.2 Gen 2 (10Gbps); a 2,000MB/s SSD needs Gen 2x2 (20Gbps), which few laptops and no Macs offer. On a slower port the drive simply runs at the port's speed.
