Samsungi 256 GB PM981 M.2 PCIe NVMe Performance OEM SSD (Phoenixi kontroller)

Samsung PM981 on Samsungilt tuletatud OEM-toode 970 EVO.

Sellel draivil on Samsungi uus 64-kihiline V-NAND ja suure jõudlusega kontroller, mis tagab kuni 3,000 MB/s järjestikuse lugemise läbilaskevõime ja 270,000 juhusliku lugemisega IOPS.

Varajases versioonis kasutati Samsung Polaris V2 mälukontrollerit, but ARM Phoenix memory controller was used in the later version.

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