Description
The NM620 is the argument for reading past the interface number. It is PCIe 3.0, so peak sequential read is lower than the PCIe 4.0 budget drives — but it uses TLC rather than QLC, and its 500 TBW endurance is more than double the Crucial P3 Plus at the same capacity. On an older board, none of the PCIe 4.0 headroom would have been usable anyway.
Key specifications
- Sequential 3300 MB/s read, 3000 MB/s write
- 500 TBW endurance, 5-year limited warranty
- 3D TLC NAND, DRAM-less (HMB), single-sided M.2 2280
- PCIe 3.0 x4, NVMe 1.4
Where it fits
Fleet upgrades on PCIe 3.0 platforms, budget system drives that still need TLC endurance, and laptop refits.
Trade notes
Retail-boxed. The strongest margin position in the value tier here — worth leading with when the customer has asked for "cheap NVMe" and the machine is a PCIe 3.0 platform.
