In the future if I need to buy more disks… how can I replace disks?
There are two options for you. You can either add additional drives in the empty bays (or in the expansion box) or replace smaller drives with bigger ones. Accordingly in the settings – storage pool management select “Add Disk” to add additional drive. If you want to replace disks with bigger capacity drives then select “Replace disks one by one”. Instructions bellow.
Log in to QTS with an administrator account. Go to “Storage Manager” > “Storage Space“. Select the storage pool that will be expanded, then click “Manage“. The “Storage Pool Management” window will appear, select the RAID group that will be expanded and click “Replace Disks One by One” in the “Manage” menu.
Highlight the first disk to be replaced, and click “Change“.
What drives should I use?
Preferably you should try to use similar spec drives. If you have WD Red 4TB, get WD 6TB. If it is Seagate 7200RPM tro to use bigger HDD but with the same RPM.
