@th3j35t3r I've had very weird success with raid, I don't know if I did mine correctly at all but my PC likes to take a second try to boot sometimes, and when it does boot the boot record says something like "can't find hard drive" shortly before booting to windows lol

If I have to shut the PC down in an emergency or the power goes out, it goes into a repair mode where it checks that both volumes of the raid (mirrored 2 TB drives) are still duplicated. Slows the whole thing down for hours.
