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

Samsung PM981 je izdelek OEM, ki izhaja iz Samsunga 970 EVO.

Ta pogon ima Samsungov novi 64-slojni V-NAND in visoko zmogljiv krmilnik, ki zagotavlja do 3,000 MB/s zaporedne prepustnosti branja in 270,000 IOPS naključnega branja.

Pomnilniški krmilnik Samsung Polaris V2 je bil uporabljen v zgodnji različici, but ARM Phoenix memory controller was used in the later version.

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