for outstanding and completed portions of the workload. The
RAID Controller allows user to choose the SATA Mode: SATA150,
SAT150+NCQ, SAT300, SATA300+NCQ.
3.7.5.7 Disk Write Cache Mode
User can set the “Disk Write Cache Mode” to: Auto, Enabled or
Disabled.
3.7.5.8 Capacity Truncation
ARECA RAID controllers use drive truncation so that drives from
differing vendors are more likely to be able to be used as spares
for each other. Drive truncation slightly decreases the usable
capacity of a drive that is used in redundant units.
The controller provides three truncation modes in the system
configuration: Multiples Of 10G, Multiples Of 1G, and No
Truncation.
