  • Rated 1 out of 5 stars

    Fast but not reliable.

    Very disappointed. First, the controller does not report correctly in Windows 11. Also, disk optimizer sees it as a hard drive. It is very fast, and it appears to store the data correctly. However, the corrupted or malfunctioning firmware does not give me the warm fuzzies regarding the data I put on the drive. Crucial's storage executive reports the firmware is up to date, but has other issues identifying it as a Crucial drive, or micron, in its toolset. This was a lot of money for something that only appears to half-work. As an FYI, I tested my Samsung 2TB in the same 3.2 USC C plug and everything was flawless. So, I guess if I have 4TB of data I don't worry about losing I may use this someday, but leaves a bad taste in my mouth in regards to Crucial.
