What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Crucial X10 Pro Portable SSD
Three whitelisted testers (Tom's Hardware, StorageReview, PCWorld) all lab-benchmarked the 2TB Crucial X10 Pro and recommend it: the fastest real-world 20Gbps USB SSD they tested, near Thunderbolt 3 in file transfers, with strong sustained writes. Caveats: it trails rival Gen 2x2 drives in synthetics and needs a rare USB 3.2 Gen 2x2 port. (3 sourced reviews, 3 lab-tested.)
Praised: Fastest / class-leading real-world 20Gbps USB performance, rivaling Thunderbolt 3 in file transfers; Excellent sustained write performance for large-file creative workloads; Compact, solid, IP55-rated metal shell at a reasonable price.
Flagged: Needs a rare USB 3.2 Gen 2x2 port; halves to 10Gbps on Thunderbolt/standard ports; Trails competing Gen 2x2 drives and Thunderbolt in synthetic/random benchmarks; Write speed collapses (to ~50MBps) once the SLC cache is fully exhausted.
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.
