What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 3 lab-tested.)
Praised: Sequential throughput lands at or near the ~1,000 MB/s practical ceiling of the 10 Gbps interface; Compact, rounded pebble-shaped body with non-slip feet on the bottom; Metal shell feels rugged and solid in the hand.
Flagged: Sustained write collapses once the secondary cache is exhausted on large continuous transfers; Priced above competitors that are equally fast or faster; Middling PCMark 10 result — lands in the lower half of the 2024 comparison set.
