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?
JBOD relies on an optional SATA extension, which most of your controllers won’t have.
That leaves you with RAID in the controller - which is a bad idea, as you don’t have much control over what is going on, and recovery if it fails will possibly messy.
Then why does it list JBOD?
Because it does JBOD if the controller supports it. Pretty much none of the controllers you’ll find in consumer hardware support that.
What do you mean by “controller”?
The SATA controller on the motherboard. The thing you plug your SATA cable into.
