Adding a second HDD to the ReadyNAS Duo expanding total storage capacity
I've been looking a bit on the internet, and it appears, that adding an additional disc to the 2nd bay (out of 2), it will be a disc that is used for some sort of "backup" of disc 1, in case it malfu...

Will this turn out as I fear, stated above, or will this make me able to have a total of 2TB og storage on my NAS?
You will end up with the same 1 TB volume size you have now. Lundmilo did a nice job of explaining the benefits. Even with xraid, you still need backups to keep your data safe.
If you want 2 TB of space, then you have options:
(a) buy two 2 TB disks (for instance WD20EFRX), and replace your current drives. You'd do that one at a time with the NAS running (making sure that the resync for the first drive completes before you do the second). It'll cost you a little bit, but this is the easiest way.
(b) save all your data on a backup disk. Then remove one drive and do a factory reset. You have about 10 minutes after you initiate the reset to go into the NAS setup with RAIDar and select flex-raid (raid-0). After the setup completes, you can add a second drive, and create a separate "d" volume. Create some shares on each volume, and restore the data from your backup disk.
Note the need for backup on (b) - the reset will destroy all your existing data. You'll also need to redo the configuration and reinstall any add-ons.
