• Max SATA Mode Supported
Within the RAID controller, the host eSATA / USB 2.0 chan-
nels act as a target and 4 Serial ATA ll bus are connected to the
drive. The SATA ll 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.
• 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 compatible
with EliteRAID RAID controller, 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 following host NCQ mode setting.

No NCQ support

•
HDD Read Ahead Cache
Allow Read Ahead (Default: Enabled)—When Enabled, the drive’
s read ahead cache algorithm is used, providing maximum
performance under most circumstances.
•
Volume Data Read Ahead
The volume ,read data ahead parameter specifies the controller
firmware algorithms which process the Read Ahead data blocks
from the disk. The Read Ahead parameter is normal by default.
