Samsung 256 GB PM981 M.2 PCIe NVMe Performance OEM SSD (Controlador Phoenix)

Samsung PM981 é o produto OEM derivado de Samsung 970 Evo.

Esta unidade presenta o novo V-Nand de 64 capas de Samsung e un controlador de alto rendemento que achega 3,000 MB/s de rendemento de lectura secuencial e 270,000 IOPS de lectura aleatoria.

O controlador de memoria Samsung Polaris V2 utilizouse na versión temperá, but ARM Phoenix memory controller was used in the later version.

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