I know how RAID work and prevent data lost from disks failures. I want to know is possible way/how easy to recover data from unfunctioned remaining RAID disks due to RAID controller failure or whole system failure. Can I even simply attach one of the RAID 1 disk to the desktop system and read as simple as USB disk? I know getting data from the other RAID types won’t be that simple but is there a way without building the whole RAID system again. Thanks.

    Are there differences in the context of failure, when using a controller vs software raid with mdadm?

      With software raid, there is no controller to fail.

      Well, that’s not strictly true, because you still have a SATA/SAS controller, HBA, backplane, or whatever, but they’re more easily replaceable. (Unless it’s integrated in the motherboard, but then it’s not a separate component to fail.)
