Crucial P310 2TB M.2 NVMe SSD CT2000P310SSD8

5.8/10verdict: good, not the best

The Crucial P310 2TB is for desktop and laptop builders who want rated speeds of 7,100 MB/s read and 6,000 MB/s write in a single-sided M.2 2280 PCIe 4.0 drive. It suits game libraries, OS drives and general storage that is mostly read rather than rewritten. It is a poor fit for write-heavy homelab or workstation duties, because its rated endurance is low.
