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

Samsung PM981 ir OEM produkts, kas iegūts no Samsung 970 EVO.

Šajā diskdzinī ir Samsung jaunais 64 slāņu V-NAND un augstas veiktspējas kontrolieris, kas nodrošina līdz pat 3,000 MB/s secīgas lasīšanas caurlaidspēja un 270,000 nejauši nolasīts IOPS.

Samsung Polaris V2 atmiņas kontrolieris tika izmantots sākotnējā versijā, but ARM Phoenix memory controller was used in the later version.

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