I bought one of these and now I'm unclear what I should be doing regarding RAID. Can I not add drives later?
I'm not sure if I'm looking at old data but I'm starting to feel stupid. I'm not super tech literate but I'm typically above average. Also a lot of doom and gloom telling me redundancy isn't a backup like I don't already know.
You can add drives later and you can also change the RAID type later when adding a drive.
Online RAID Level Migration supports the following RAID migrations:
Single drive to RAID 1
RAID 1 to RAID 5
RAID 5 to RAID 6
But you can only migrate to a different RAID within that scheme when adding 1 drive, as the new drive will be used to create that new RAID level. Changing the RAID type otherwise will require making every fresh and all data will be removed.
