System Setup Program
Another advantage of a RAID level 0 configuration is that it utilizes the full capacities of the drives. For
example, if you have two 120-GB drives installed, you have 240 GB on which to store data.
NOTICE:
Because RAID level 0 configurations provide no data redundancy, if one drive fails, then the data on the
other drive is also inaccessible. Therefore, ensure that you perform regular backups when you use a RAID level 0
configuration.
RAID Level 1 Configuration
RAID level 1 uses a data-redundancy storage technique known as "mirroring." When data is written to
the primary drive, it is then duplicated, or mirrored, on the other drive. A RAID level 1 configuration
sacrifices high data-access rates for its data redundancy advantages.
