장터에서 구입한 ioScale2 825GB 모델을 2주 정도 사용 중인데, 무식한 내구성 덕분에 다운로드 전용 디스크로 활용하고 있습니다.

그런데 이상한 것이 전송 속도가 너무 안 나오는 것입니다...명색이 PCIe 타입의 NVMe SSD인데 말입니다...

그래서 속도를 측정해봤는데...


[랜덤쓰기]


[제로필]


이거 완전 HDD 전송 속도가 나오는 겁니다...

기기 자체의 문제는 아닌 것 같고 드라이버 문제 쪽으로 추측할 뿐인데...

관리자 페이지인 셈인 Dell ioSphere에 들어가봐도 뭘 어떻게 설정해줘야 하는지도 모르겠구요...

혹시 아래의 자료이면 뭐가 문제인지 알 수 있을까요...?

너무 심각하게 느려서 이거 참...
