## What reviewers say

Four whitelisted testers (StorageReview, Tom's Hardware, TechRadar, PCWorld) hands-on benchmarked the 2TB model. Verdict: fast, premium, and rugged with reads that leave USB 3.2 drives well behind, but sustained and single-thread writes lag cheaper rivals like Corsair's EX400U, and it runs pricey and bulky. Non-whitelist outlets were excluded. (Based on 4 reviews, 4 lab-tested, 2025-03-16–2025-10-28.)

Praised: Fast sequential read speeds, close to the advertised 3,800 MB/s and well ahead of USB 3.2 Gen 2x2 drives; Premium, rugged IP65 build with 2m drop protection that looks and feels high-end; 5-year warranty, longer than most USB4 rivals.
Flagged: Weak single-thread and sustained/small-file write performance versus rivals; Physically large and heavy (~172g) for a modern portable SSD; Priced above the faster, cheaper Corsair EX400U; USB4/Thunderbolt interoperability quirks; dropped to 10/5 Gbps links on some hosts.
Disagreement: Testers split on value: PCWorld calls it 'decently affordable for USB4' and says 'price is not an issue,' whereas Tom's Hardware ('hard to recommend') and TechRadar ('47% more expensive than the EX400U') judge it overpriced against Corsair's cheaper, faster drive.
