1.3.3 RAID storage specifications

The Aurora has a sophisticated built in RAID software and drives that are pre-
configured and prepared for you so it would be plug and play for most users.
By default, the Aurora RAID has been configured into one RAID 6 logical
volume. For 32 bit Windows XP configurations, our special setting allow over
2TB volumes to be created for you.
RAID 6 with its dual parity drive protection has been found to be the most
protective and least costly way of guarding against not only initially failed
SATA disk drives but primarily against the total loss of the RAID data because
a second SATA drive detects an error during the RAID rebuild process. A
RAID 5 configuration in that scenario would cause the RAID not to rebuild
properly.
