Thoughts on these SATA/M.2-->SATA/2.5" adapters?
(feddit.nl)
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?
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.
