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

Samsung PM981 Samsung компаниясынан алынган OEM продуктусу 970 EVO.

Бул дискте Samsungтун жаңы 64 катмарлуу V-NAND жана жогорку өндүрүмдүүлүктөгү контроллери бар. 3,000 Мб/с ырааттуу окуу өткөрүү жөндөмдүүлүгү жана 270,000 кокус окуу IOPS.

Samsung Polaris V2 эстутум контроллери алгачкы версиясында колдонулган, but ARM Phoenix memory controller was used in the later version.

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