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

Ang Samsung PM981 mao ang OEM Product nga nakuha gikan sa Samsung 970 Evo.

Ang kini nga pagmaneho adunay bag-ong 64 nga layer sa Samsung V-Nand ug usa ka high-performance controller nga naghatag sa 3,000 MB / S sa sunud-sunod nga pagbasa sa o 270,000 Random Basaha ang Iops.

Ang Samsung Polaris V2 Memory Controller gigamit sa sayo nga 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.
