Can I turn two single disks plus a new drive into raid 5 without losing data?

Hello folks,

I have a TS-451+ with 1 12TB drive and a 4TB drive both are "RAID Type: Single" in one data volume.

The 4TB drive is degrading so i'm replacing it. I was thinking of getting 2 new 12TB drives, so a total of 3 12tb drives.

Can I migrate the two drives I have to raid 5 with the new drives ill be buying?

Is Raid 5 the best idea so that i dont lose any data?

if useful:
Drive 1: capacity 10.90TB
Drive 2: capacity 3.63TB
total used: 10.30TB

thanks for any tips and help.

You can upgrade a first 12tb with raid1 using a first 12tb.
Copy everything from the 4tb to this new array.
Remove the 4tb and place a 12tb and convert the raid1 to raid5.

Right now the two disks are in one data volume, how do I separate the two disks?

Oh, did not analyse it correctly!

I would then put a 12tb in the third bay.
Copy everything from the two first drive on it.
Then remove your previous array/volume.
Reuse your first 12tb bay and upgrade your third bay with in into a raid1.
After put the last 12tb to replace the 4tb into second bay.
And upgrade from raid1 to raid5.
