Crucial P3 NVMe M.2 SSD, Up to 3,500MB/s Read, PCIe 3.0, 500GB–4TB

A Gen3 x4 drive, and that is the case for buying it: where the host slot is itself Gen3 — older boards, most pre-2021 laptops — a Gen4 card returns nothing for the extra money.

The flash is QLC with no onboard DRAM, so bulk writes slow considerably once the SLC cache is exhausted. As a capacity or game drive it is well judged; for editing scratch space, the Crucial P5 1 TB CT1000P5SSD8 Internal Solid State Drive uses TLC with a cache.
