सैमसंग 256GB PM981 M.2 PCIe NVMe परफॉर्मेंस OEM SSD (फीनिक्स नियंत्रक)

Samsung PM981 is the OEM product derived from Samsung 970 EVO.

This drive features Samsung’s new 64-layer V-NAND and a high-performance controller that delivers up to 3,000 MB/s of sequential read throughput and 270,000 random read IOPS.

Samsung Polaris V2 memory controller was used in the early version, but ARM Phoenix memory controller was used in the later version.

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