- Spec source
- Maker's datasheet
Specifications from the maker’s own datasheet. A dash or a missing row means the maker does not publish that figure for this capacity.
Does it fit a PS5?
No. It misses one of Sony's requirements: PCIe Gen4 or faster on four lanes, M.2, at least 5,500 MB/s, and no taller than 11.25 mm with a heatsink. Every drive that fits.
Quality score
How we score →Scored for a gaming PC from what the maker publishes: read speed against the level games are built around, capacity (under 1TB loses points), cache type, endurance per terabyte and warranty. Speed above the floor adds almost nothing.
A factor we hold no value for scores zero rather than being skipped, so a drive we know little about never outranks a fully documented one. A low score with low confidence means undocumented, not bad. This is a specification index, not a benchmark, and it only compares NVMe SSDs with each other.
