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

Samsung PM981 သည် Samsung မှဆင်းသက်လာသော OEM ထုတ်ကုန်ဖြစ်သည်။ 970 EVO.

ဤ drive တွင် Samsung ၏ 64-layer V-NAND အသစ်နှင့် စွမ်းဆောင်ရည်မြင့် controller တို့ပါရှိသည်။ 3,000 စဉ်ဆက်မပြတ် ဖတ်ရှုမှုနှုန်း၏ MB/s နှင့် 270,000 ကျပန်း IOPS ကိုဖတ်ပါ။.

Samsung Polaris V2 memory controller ကို အစောပိုင်းဗားရှင်းတွင် အသုံးပြုခဲ့သည်။, but ARM Phoenix memory controller was used in the later version.

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