Samsung 256GB PM981 M.2 PCIe NVMe کارکردگی OEM SSD (فینکس کنٹرولر)

Samsung PM981 Samsung سے اخذ کردہ OEM پروڈکٹ ہے۔ 970 ای وی او.

اس ڈرائیو میں سام سنگ کا نیا 64 لیئر V-NAND اور ایک اعلی کارکردگی والا کنٹرولر ہے جو 3,000 ترتیب وار پڑھنے کے تھرو پٹ کا MB/s اور 270,000 بے ترتیب پڑھنے والے IOPS.

Samsung Polaris V2 میموری کنٹرولر کو ابتدائی ورژن میں استعمال کیا گیا تھا۔, but ARM Phoenix memory controller was used in the later version.

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