RAID 5
D&D writes
414 Mbps
507 Mbps
RAID
 
5 offers the highest usable 
capacity when performance is not 
important. Additionally, RAID
 
offers lower redundancy than 
other RAID types that are listed in 
this table. Accordingly, 
designation of a hot spare disk is 
highly recommended. Use RAID
 
only for data archiving and 
backup applications.

RAID 6+0 x3
This volume consists 
of four disks that have 
been expanded two 
times for a total of 
three RAID groups.
D&D writes
455 Mbps
591 Mbps
RAID 6+0 delivers higher 
performance than RAID
 
5 or 
RAID
 
6, but is recommended only 
for storage applications that are 
not sensitive to latency.
