    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.

    I was running out of space on my hard drive, so decided to give this a try, to keep it plugged in at all times and load games from it. Turns out, it loads faster than from the HDD! Just make sure to plug it into a USB 3.2 or better port. Totally worth it!

    Only downfall is it didn’t come with a usb c adapter. Not a lot of pcs are made with them . They are still fairly new technology.
