Looking for suggestions on setting up my ReadyNAS314, and choosing the right RAID setup
I've been using my ReadyNAS 314 for a long time now, with 4 x 3TB WD drives, in a RAID 5 configuration. Recently I started running out of space, so I bought a single 10TB drive to replace one of the ...
Using X-RAID you'd need two of the 3TB disks replaced with 10TB disks not just one to vertically expand your volume.
Thanks - I was afraid that this might be the only solution, as it is quite expensive. There is no option to have one disk be separate from the others then, with a ReadyNAS?

No. You can not take drives out of an active RAID array without the volume being degraded. If you have a RAID 5 with 4 drives then all data is spread out over all 4 drives so that if any drive fails the data can be restored from the remaining 3 drives.
If you wish to go from 4 to 3 drives in your array then I'm afriad there is no other way than to backup destroy the volume and restore the data back.
You can create a separate volume for the 10 TB drive (and not protect that volume with RAID).
Getting there from where you are would require a factory reset, rebuilding the NAS, and restoring the data from backup.
You're 10TB drive is stuck as is until you either add a second 10TB drive to take advantage of that extra space or redo your Raid again with the 3 other drives using a Flex-Raid setup and then using the 1 TB drive alone. of course you would have no safetly net with a single HDD by it's self, but it is doable. It's just to late now.
Next time, you, and this goes for others, you can check out this handy web page Netgear created called the RAID Calculator. Which looks like it has recently been updated to 12 TB HDD's. The last time I saw it a couple weeks ago it only wewnt to 8TB. So using it, you can see what kind of results you have popping in 1 HDD or more then one and of differnt sizes. So if you used this before hand, you would have saw that most of that 10TB HDD would not have been used until you popped in a second 10TB HDD. You can also compair from a XRaid setup to a Flex-Raid setup.

You do need to be careful here - the tool doesn't show you upgrade "what-ifs", it only shows you what space you'd get if you did a factory install with those drives in place.
For instance if he replaced a 3 TB drive with a 2 TB drive, the tool would show a 1 TB drop off in capacity. But if he did it in a real system, he'd end up with a degraded volume.
You mean that NAS would actually try to do something with that smaller HDD instead of just ignoring it? Again is case people don't know, you can go same size HDD or larger, you can't go to a smaller HDD or remove a HDD without starting over brand new. Again I figured the NAS was smart enough that it would ignore a HDD thrown in that was smaller. Not just try to use it and fail and screw things up. It doesn't make a whole lot of sense to allow something like that to happen. After all it should be a simple check of the drive size before doing anything with it.
