Samsung 256GB PM981 M.2 PCIe NVMe Performa OEM SSD (Pengendali Phoenix)

Samsung PM981 adalah produk OEM turunan dari Samsung 970 EVO.

Drive ini dilengkapi V-NAND 64-lapisan baru dari Samsung dan pengontrol berkinerja tinggi yang mampu memberikan hingga 3,000 MB/s throughput baca berurutan dan 270,000 membaca IOPS secara acak.

Pengontrol memori Samsung Polaris V2 digunakan pada 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.
