information. If any drive fails, data on the failed drive can be rebuilt from the parity
bit data on other drives in the array. RAID 5 requires at least 3 drives. The
advantages are better utilization of the capacity of all redundant drives configured
in the array and excellent read/write performance. Note that drive failures will
affect the throughput rate. This means a longer time is required to rebuild data
than it takes in RAID 1 configuration.

RAID 6
Compared with RAID 5, RAID 6 adds a second independent parity block for double
parity. The two independent parity systems use different algorithms to ensure high
data reliability. Data processing is not affected even if two drives fail at the same
time. However, RAID 6 requires larger drive space for storing parity information
and has a higher "write penalty" compared with RAID 5. Therefore, RAID 6 provides
lower write performance than RAID 5.
