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.

    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
