Samsung 256GB PM981 M.2 PCIe NVMe Performance OEM SSD (Phoenix stjórnandi)

Samsung PM981 er OEM varan frá Samsung 970 EVO.

Þetta drif er með nýja 64 laga V-NAND frá Samsung og afkastamikilli stýringu sem skilar allt að 3,000 MB/s af raðaflestri og 270,000 af handahófi lesið IOPS.

Samsung Polaris V2 minnisstýringin var notuð í fyrstu útgáfunni, but ARM Phoenix memory controller was used in the later version.

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