RAID 0 STRIPING
Striping connects
several drives to one large virtual drive as a logical
unit
. The data is written
parallel
onto all hard drives, which results in an
increased data-transfer-rate. When one drive fails or gets damaged all data
will be lost and can only be reconstructed with professional help. The usab-
le memory corresponds to the memory of the smallest drive times two. For
this mode we recommend to use two identical hard drives (same capacity,
brand and model-number).
RAID 1 MIRRORING
Mirroring is the
automatic copying of data onto several hard drives
. This
ensures high reliability of the data network in the event of a hard drive failu-
re. In case of failure of one disk access is still possible and after exchange
of the failed drive the data will be restored. The usable memory corresponds
to the memory of the smallest drive.
For this mode we recommend to use two identical hard drives (same capa-
city, brand and model-number).
