The PM981 is Samsung's OEM PCIe 3.0 x4 NVMe drive in the M.2 2280 form factor, built on 64-layer TLC NAND with the Phoenix controller. Sequential reads reach around 3,000 MB/s and writes around 1,800 MB/s, which is close to the retail 970 EVO of the same generation but without Samsung's consumer warranty or Magician support. It suits laptop and desktop upgrades and secondary game or scratch drives where capacity per dollar matters more than peak Gen4 speed. Buyers rate it well, though the lack of a retail warranty and the DRAM-less reputation of some OEM batches come up in discussion.
