Samsung 256GB PM981 M.2 PCIe NVMe Prestasie OEM SSD (Phoenix beheerder)

Samsung PM981 is die OEM-produk afkomstig van Samsung 970 EVO.

Hierdie aandrywer beskik oor Samsung se nuwe 64-laag V-NAND en 'n hoëprestasiebeheerder wat tot 3,000 MB/s van opeenvolgende lees deurvoer en 270,000 ewekansige lees IOPS.

Samsung Polaris V2 geheuebeheerder is in die vroeë weergawe gebruik, but ARM Phoenix memory controller was used in the later version.

It was popular for a while because of its good value for money.
