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 think it had its uses in the past, specifically if it had the memory backup to prevent full array rebuilds and cached data loss on power failure.
Also at the height of raid controller use (I would say 90s and 2000s) there probably was some compute savings by shifting the work to a dedicated controller.
In modern day, completely agree.
