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.

    Lots of people have moved away from raid entirely because of some of these issues. There are alternatives these days. For example mergerfs or the ZFS file system.

      Can confirm that moving a zfs array to a new system after a failure is simply connect the disks and zpool import -f <pool_name>

      Every raid card I use now is put in hba mode it’s just simpler to deal with

        Not to mention hardware raid is dependent on a functional card. You are in trouble if the card has problems. Also hardware raid doesn’t do data validation

          I feel like hardware raid is relic from the pre multi core CPU days, given that was less than 20 years ago it makes me feel old

      You are describing software raid which is the only thing really used these days. There are so many issues with hardware raid.
