Press “Enter” key to define fast initialization or Selected the 

Background (Instant Available). When background Initialization, 

the initialization proceeds as a background task, the volume set 

is fully accessible for system reads and writes. The operating 

system can instantly access to the newly created arrays without 

requiring a reboot and waiting the initialization complete. when 

Fast Initialization, the initialization proceeds must be completed 

before the volume set ready for system accesses.

This parameter sets the size of the stripe written to each disk in 

a RAID level 0, 1, 1E, 5 or 6 logical drive. You can set the stripe 

size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.

A larger stripe size produces better read performance, espe-

cially if your computer does mostly sequential reads. However, 

if you are sure that your computer does random reads more 

often, select a smaller stripe size.

Note: RAID level 3 can’t modify strip size.

The SATA RAID controller supports Write-Through Cache and 

Write-Back Cache.

 

SCSI Channel: The SATA RAID controller function is simulated 

as a SCSI RAID controller. The host bus is represented as a 

SCSI channel. Choose the SCSI Channel. 

SCSI ID: Each SCSI device attached to the SCSI card, as well 

as the card itself, must be assigned a unique SCSI ID number. 

A SCSI channel can connect up to 15 devices. The SATA RAID 

controller is a large SCSI device. Assign an ID from a list of 

SCSI IDs.  

SCSI LUN: Each SCSI ID can support up to 8 LUNs.  Most SCSI 

controllers treat each LUN like a SCSI disk.

The Enabled option is useful for enhancing overall system 

performance under multi-tasking operating systems. The Com-

mand Tag (Drive Channel) function controls the SCSI com-

mand tag queuing support for each drive channel. This func-
