## What reviewers say

**SK Hynix Beetle X31 Portable SSD** — Solid but not class-leading. Three testers benchmarked it hands-on — PCWorld (July 2023) and StorageReview (February 2024) on 1TB, Tom's Hardware (December 2024) on 2TB. All three measured sequential throughput at or near the practical ~1,000 MB/s ceiling of the 10 Gbps interface, and all three note the compact rounded shell with non-slip feet. The two outlets that ran long continuous writes both hit a cache cliff. Pricing is contested rather than agreed: two outlets call it expensive, one calls it market-rate. (3 sourced reviews.)

**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. (1 sourced review.)
