RAID 1
RAID 1 mirrors the data in blocks on the two disk drives, so the exact
same data is stored on both drives. Data integrity is more reliable
in this mode than in RAID 0 mode, although there is less accessible
disk space and the transfer speed is slower. Mirroring makes it
easier to recover lost data if one of the RAID drives is damaged (see
Troubleshooting on page 16). Only one of the two drives is accessible
in RAID 1 mode.
Figure 2. RAID 1 mode, only one drive will appear on your computer.
When using RAID 0 and RAID 1 modes, you can use disk drives
of varying capacities, although the capacity will be limited to the
smallest of the disk drives. For example, if you are using a 100 GB and
a 250 GB drive, then the 250 GB will be limited to the smaller 100 GB
capacity, and the total combined capacity will be 200 GB.
