Samsung PM981 huwa l-prodott OEM derivat minn Samsung 970 EVO.
Din id-drajv fiha l-V-NAND ġdid ta’ 64 saff ta’ Samsung u kontrollur ta’ prestazzjoni għolja li jwassal sa 3,000 MB/s ta' qari sekwenzjali u 270,000 IOPS aqra bl-addoċċ.
Il-kontrollur tal-memorja Samsung Polaris V2 intuża fil-verżjoni bikrija, but ARM Phoenix memory controller was used in the later version.
It was popular for a while because of its good value for money.
