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.
I’d stay away from hardware RAID controllers. If they fail you’re gonna have a hard time. Learned that the hard way. With a software RAID you can do what you proposed. Just put the disk in another system and use it there.
Seconded. Software RAID is much easier to recover from.
