WARNING
Description
Check the boxes of the hard drives you wish to add to the
storage volume.
Check a box to designate the replacement HDD for the storage
volume. This becomes the backup for any damaged hard drives.
This sets the stripe size to maximize performance of sequential
files in a storage volume. Keep the 64K setting unless you
require a special file storage layout in the storage volume. A
larger stripe size is better for large files.
Press this button to add a new Spare disk.
Press this button to configure a file system and create the RAID
storage volume.
