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

Samsung PM981 dia vokatra OEM avy amin'ny Samsung 970 EVO.

Ity fiara ity dia manasongadina V-NAND vaovao misy sosona 64 an'ny Samsung ary fanaraha-maso avo lenta izay manome hatramin'ny 3,000 MB/s amin'ny famakian-teny misesy sy 270,000 kisendrasendra mamaky IOPS.

Samsung Polaris V2 mpanara-maso fahatsiarovana dia nampiasaina tamin'ny dikan-teny voalohany, but ARM Phoenix memory controller was used in the later version.

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