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

Samsung PM981 hè u pruduttu OEM derivatu da Samsung 970 EVO.

Questa unità presenta u novu V-NAND di 64 strati di Samsung è un controller d'alta prestazione chì furnisce finu à 3,000 MB/s di velocità di lettura sequenziale è 270,000 lettura casuale IOPS.

U controller di memoria Samsung Polaris V2 hè stata utilizata in a prima versione, but ARM Phoenix memory controller was used in the later version.

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