RN204 adding smaller disk
I just got an RN 204 and have been migrating all of my data to it. it's on latest firmware 6.4.2 I think, have 2x5TB drives in it, and am running the default X-Raid. I'm finishing off moving everything from a 4TB drive in my desktop and would like to add the soon to be empty, 4TB drive to the array to expand the total available storage. However, I don't think this will work and would reduce my total available storage to 3x4TB / 2 = ~6TB vs what I would like is ~7TB total available storage. Can someone confirm what will happen if I add the 4TB drive to the 3rd bay? - Thanks!
The ReadyNAS won't add the smaller drive to the array. You could switch to flexraid and add it as a separate (jbod) volume.
FWIW, if you did a factory reset with all drives in place you'd end up with 9 TB of storage (~8.2 TiB). The rule is to sum the drives and subtract the largest.

Thank you. Will keep the 4TB drive in my PC and use that as a backup for the important stuff.
