Samsung 256GB PM981 M.2 PCIe NVMe Feidhmíochta OEM SSD (Rialaitheoir Fhionnuisce)

Is é Samsung PM981 an táirge OEM a dhíorthaítear ó Samsung 970 EVO.

Tá V-NAND 64-ciseal nua Samsung agus rialtóir ardfheidhmíochta a sheachadann suas go dtí an tiomántán seo le fáil. 3,000 MB/s de thréchur léite seicheamhach agus 270,000 IOPS a léamh go randamach.

Baineadh úsáid as rialtóir cuimhne Samsung Polaris V2 sa leagan luath, but ARM Phoenix memory controller was used in the later version.

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