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.

It's still in box and considering returning it.

Any advice? Sorry for the vague question.

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.

Ok, I think I get all that. It seems I was just over thinking things. Thanks.
