I bought two WD30EFRX (3TB) to replace the 1TB drives. I have a good backup of my ReadyNAS data and am ready to proceed with replacing the drives. Is the following a good approach? Upgrade to latest version of RAIDiator Do a config backup Remove both 1TB drives Install both 3TB drives Perform factory reset per instructions on link you provided above Restore Config backup * Can I then put one of the 1TB drives in bay 1 and let it sync to the new 3TB drive in bay 2 to restore the data? After it syncs, move the 3TB drive from bay 2 to bay 1, install the second new 3TB drive in bay 2 and let it sync?

If ever that your RND2110 is a ReadyNAS Duo v1, I believe 3TB drives are not supported as per the HCL. Since I do not own a ReadyNAS Duo v1, I could say that it may or may not work.

For vertical expansion, I would suggest to pull-out disk1 then insert the new drive then let it resync. After the resync process has completed, pull-out disk2 then insert the other new disk then let it resync again.
