Samsung PM981 waa badeecada OEM ee laga soo qaatay Samsung 970 EVO.
Wadaadkani waxa ku jira Samsung-ka cusub ee 64-lakabka ah ee V-NAND iyo kontaroole hawlkar ah oo bixiya ilaa 3,000 MB/s ee akhrinta xidhiidhsan iyo 270,000 akhriska random IOPS.
Xakamaynta xusuusta Samsung Polaris V2 ayaa loo adeegsaday noocii hore, but ARM Phoenix memory controller was used in the later version.
It was popular for a while because of its good value for money.
