What owners and reviewers say
Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- A premium aluminium enclosure with a near-silent cooling fan, which exceeded its rated transfer speeds in testing.
- Ships with an enterprise-class drive inside, supports several interfaces, and carries a five-year warranty with rescue service.
Commonly criticised
- Sequential write speed in one test fell well below its read speed.
- Performance is still bound by spinning-disk limits, and the premium build carries a premium price.
