Another advantage of a RAID level 0 configuration is that it utilizes the full capacities of the drives. For example, if you have two 100-GB drives installed, you have 200 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.
