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

Samsung PM981 minangka produk OEM sing asale saka Samsung 970 EVO.

Drive iki nampilake V-NAND 64-lapisan anyar Samsung lan pengontrol kinerja dhuwur sing ngirim nganti 3,000 MB / s saka urutan diwaca throughput lan 270,000 acak maca IOPS.

Pengontrol memori Samsung Polaris V2 digunakake ing versi awal, but ARM Phoenix memory controller was used in the later version.

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