Does it fit a PS5?
Yes. It meets Sony's requirements: PCIe Gen4 or faster on four lanes, M.2, and at least 5,500 MB/s. Sony recommends adding a thin heatsink, which the PS5 slot has room for. 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.
Value weighs the score against the price, compared with other 4TB NVMe SSDs: this drive costs $112.25/TB against a typical $163.98/TB. At a typical price, value equals the score. Cheaper raises it and dearer lowers it, but price counts for less than quality.
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.
