## What reviewers say

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. (Based on 3 reviews, 3 lab-tested, 2023-07-04–2024-12-16.)

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; Beat the other 10 Gbps drives in its comparison set on transfer tests; Generous accessory pack — both USB-C and USB-A cables plus a silicone bumper.
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; Thicker than slimmer rivals from Crucial and Silicon Power; Included silicone bumper lifts the anti-slip feet so the drive slides on a desk; No keyring or lanyard attachment point.
Disagreement: Two real splits. On competitive standing: PCWorld (July 2023, 1TB) called it "currently our top 10Gbps performer", and StorageReview (February 2024, 1TB) had it pulling ahead of the Crucial X9 Pro and Samsung T7 Shield on most tests — but Tom's Hardware (December 2024, 2TB) put its 1001 PCMark 10 score "in the lower half of our comparison drives", beaten by a Silicon Power PX10 that costs less. Eighteen months of newer rivals and a different capacity plausibly explain the gap. On price: Tom's and PCWorld both call it overpriced for what it delivers, while StorageReview says it is "priced in line with the market" — though StorageReview was looking at a $89.99 1TB and Tom's at a $169 2TB MSRP. The two long-write tests also produced different post-cache floors: around 250MBps (PCWorld, 1TB) versus sub-150 MB/s (Tom's Hardware, 2TB). StorageReview ran no sustained-write test at all, so it is silent on the cache cliff.
