Samsung PM981 ni bidhaa ya OEM inayotokana na Samsung 970 EVO.

Hifadhi hii ina toleo jipya la V-NAND la safu 64 la Samsung na kidhibiti cha utendaji wa juu ambacho hutoa hadi 3,000 MB/s za mtiririko wa kusoma kwa kufuatana na 270,000 random read IOPS.

Kidhibiti cha kumbukumbu cha Samsung Polaris V2 kilitumika katika toleo la awali, but ARM Phoenix memory controller was used in the later version.

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