What reviewers say about the LaCie Rugged SSD Pro

Only one whitelisted outlet (Tom's Hardware) has a hands-on, benchmarked review of this exact Thunderbolt 3 model. It rates the drive fast and cool-running with a rugged IP67 build, but flags a small SLC write cache, a steep price (about twice a typical 10 Gbps SSD), and the lack of AES hardware encryption found on the cheaper non-Pro Rugged SSD.

Based on 1 review · 1 lab-tested · 2020-06-01

Tested by Tom's Hardware

Consistently praised

  • Competitive Thunderbolt 3 speed: ATTO ~2,450/2,130 MB/s read/write, peaking near 2.8/2.4 GB/s in iometer
  • Runs cool and avoids thermal throttling under sustained load, unlike the Samsung X5
  • Rugged IP67 build (3m drop, car-crush rated) with 5-year warranty plus Rescue data-recovery service

Commonly flagged

  • Small SLC write cache: sustained writes fall from ~2.1 GB/s to ~1.1 GB/s after roughly 25GB
  • Very expensive, about twice the cost of most 10 Gbps portable SSDs
  • Lacks 256-bit AES hardware encryption that the cheaper non-Pro Rugged SSD includes

Where reviewers disagree Only one whitelisted hands-on review exists, so no cross-source comparison is possible. Only the storage-performance numbers (ATTO, iometer, latency, IOPS, sustained write) were physically benchmarked; the IP67, 3m-drop and car-crush durability claims are LaCie's own ratings restated by Tom's Hardware, not independently stress-tested.

Its sequential performance is very good as a Thunderbolt 3 portable SSD, with performance peaking at 2,450/2,130 MBps read/write.
After writing about 25GB of data to the SSD, write speeds degraded from an average of about 2.1 GBps down to about half that, 1.1 GBps.
the Rugged SSD Pro is twice the cost of most 10 Gbps portable SSDs.
