## What reviewers say

**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.)

**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.)
