6.5 Volumes and RAID

A volume is a storage area on a disk or disks. You can create volumes on the internal disks and
external disks attached to the USB port(s). You can spread a volume across internal disks but
not between internal and external disks.
RAID (Redundant Array of Independent Disks) or JBOD is the storage method that the NSA
uses. The storage method you use depends on how many disks you have and how many
volumes you want to create. It's important that you consider this carefully as all data is deleted
when you re-create a volume.
Back up your data before deleting or re-creating a volume!
For example if you originally have one disk configured at JBOD, and you then install another
disk and want to configure the two disks to use RAID 1, you should first back up all your data
on the two disks (see the Memeo Autobackup utility on the included CD) and then restore your
data later after you create the new volume type.
Below is a table that summarizes some attributes of the various RAID levels as supported on
the NSA. For capacity and storage efficiency, "S" is the size of the smallest drive in the array,
and "N" is the number of drives in the array.

The first character must be alphanumeric (A-Z 0-9).
