Trying to squeeze some more storage in my MiniPC. I have questions about these. These use hardward RAID with selectable modes (Individual/JBOD/RAID1/RAID2).
-
If I use RAID 1 and one of the drives fails, will I know?
-
If a drive fails, and a slap in a new one, will it internally begin repairing RAID 1 again?
-
Can I use these as “individual” or JBOD and have 2 separate drives through the same connector, and use something like TrueNAS to software-RAID them?
OP should be looking at backup before considering RAID anyway, because RAID is not backup.
Correct, it’s not obvious when first diving in but the main use for RAID is increasing performance and availability by allowing up to a specific number of drive failures. For that to work, ideally in an enterprise you’d have a primary and secondary controller to mitigate that point of failure which is not typical for most homelabs and makes backup even more important.
