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

Samsung PM981 je OEM proizvod izveden iz Samsunga 970 EVO.

Ovaj disk ima Samsungov novi 64-slojni V-NAND i kontroler visokih performansi koji pruža do 3,000 MB/s sekvencijalnog protoka čitanja i 270,000 nasumično čitanje IOPS.

Memorijski kontroler Samsung Polaris V2 korišten je u ranoj verziji, but ARM Phoenix memory controller was used in the later version.

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