Expanding ReadyNAS 104
Hi, I have a 4TB in my slot1 for now, but would like to expand with some HDDs i found recently, the problem is, all of them are not equal. So i have a 2TB, 3TB, 4TB (Currently in slot1) and a fou...
The slot order doesn't matter.
The capacity rule is "sum the disks and subtract the largest". So your current 2TB+3TB+4TB should give you 5 TB - shown as ~4.5 TiB on the web admin ui. You aren't able to use 1 TB of space on the 4 TB drive. The way to maximize space is to get another 4 TB drive. That would give you 9 TB (shown as ~8.18 TiB in the web ui).
Note that you don't have RAID protection when you are adding a disk - so Netgear recommends a full backup before you do that. I agree with that advice (and would add that everyone should have a backup plan in place, since RAID isn't enough to keep your data safe).

Thank you for the reply, I will add a new 4TB as suggested. I have already taken backup of my data so am safe :)
