## What reviewers say

**WD My Passport SSD (2022)** — Two whitelisted labs benchmarked the WD My Passport SSD NVMe (1,050/1,000 MB/s, USB 3.2 Gen 2, DRAM-less Blue SN550E): Tom's Hardware (Feb 2021) and StorageReview (Sep 2020). Both call it slim, secure and fast in real-world use but note it falls ~200 MB/s short of its rated speeds and, being DRAM-less, lags DRAM-based rivals like the Crucial X8 in file-copy/moderate-dataset tests. Tom's found a small 12GB SLC cache that drops sustained writes to ~710 MBps once saturated, though the drive stays cool (45C surface). (2 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.)
