What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers noted it is officially licensed for the PlayStation 5, with a redesigned heatsink that fits the console and needs no extra cooling.
- It is one of the few licensed PS5 drives offered at very large capacities, and the top-capacity version was considered reasonable value for what it is.
- Real-world game installs and transfers were consistently smooth with no noticeable slowdowns during testing.
Commonly criticised
- Its measured PS5 benchmark result came in below the advertised rating and lower than the earlier SN850 that it effectively replaces.
- Outside of sales, its pricing was judged too high for the performance on offer, with cheaper licensed alternatives running slightly faster.
