4 .5.5.6 Maximum SATA Mode
Within the RAID controller, the eSATA/USB2.0 acts as a target
and 4 SATA ll bus are connected to the drive. The SATA drive
channel can support up to SATA ll, which runs up to 300MB/
s. NCQ is a command protocol in Serial ATA that can only
be implemented on native Serial ATA hard drives. It allows
multiple commands to be outstanding within a drive at the
same time. Drives that support NCQ have an internal queue
where outstanding commands can be dynamically rescheduled
or re-ordered, along with the necessary tracking mechanisms
for outstanding and completed portions of the workload. The
RAID controller allows user to choose the SATA Mode: SATA150,
NCQ, SAT300, NCQ.
4 .5.5.7 Host NCQ Mode Setting
NCQ is a performance enhancement for SATA II-category disk
drives, and works similarly to the way command tag queuing
(CTQ) works in SCSI command set-based disk drives. NCQ
algorithms allow I/O operations to be performed out of order
to optimize and leverage disk read/write head positioning and
ultimately overall performance. Since there are some compat-
ible with EliteRAID, It provides the following option to tune the
function. The default setting on this option is Disable for better
compatibility. The EliteRAID RAID controller provides the follow-
ing host NCQ mode setting.
