6.3 Disk

You can view information on the NSA internal disks in this screen.
Disk Replacement Restrictions
See the Quick Start Guide for information on replacing disks in the NSA. When replacing a
disk in a degraded or down RAID array, the new disk must be at least the same size or bigger
than the array's smallest disk, so the NSA can restore all data in the array. For optimal
performance, all disks in the array should be the same model, capacity, and speed.
For example, if you have RAID with 250 GB disks, you must put in a 250 GB or bigger disk as
a replacement in order to restore all original data in that array. If you use a bigger disk, the
extra space on the disk will not be used.
The NSA automatically repairs a degraded RAID if you insert an empty disk
without an existing file system. Otherwise, when you replace a disk you must
go to the Storage > Internal Storage > RAID screen, select the degraded
array, and click Repair.
