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

Ang Samsung PM981 ay ang produktong OEM na nagmula sa Samsung 970 Evo.

Nagtatampok ang drive na ito ng bagong 64-layer na V-Nand ng Samsung at isang mataas na pagganap na magsusupil na naghahatid hanggang sa 3,000 Mb/s ng sunud -sunod na basahin ang throughput at 270,000 Random basahin ang mga IOP.

Ang Samsung Polaris V2 Memory Controller ay ginamit sa maagang bersyon, but ARM Phoenix memory controller was used in the later version.

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