Red Hot RAID 6
The fastest RAID 6 available
RAID 6 eliminates the risk of data loss if a second hard disk drive fails
while the RAID array is rebuilding. In a 3ware RAID 6 system, two sets
of parity are calculated, written, and rotated across all the drives.

to survive up to two drive failures without losing data, for significantly
improvedfaulttolerance.RAID6-enabled9690SAand9650SEcontrol-
lers deliver unequaled RAID 6 performance.
RAID 6 represents a sea change in the RAID landscape. It provides
the industry with higher levels of data protection, data availability and
faulttolerancethanRAID5.Byassuringdataavailabilityfollowinga
second drive failure, users can rest assured that they are enjoying
maximum data protection, both in normal and degraded modes.
And, with RAID 6-enabled 3ware controllers, RAID 6 will not cripple
performance.

3ware RAID 6: Two sets of parity data, P + Q, are striped across
disks. RAID 6 safeguards against data loss during rebuild mode
by allowing up to two consecutive drive failures for maximum
fault tolerance.
