• Initialization Mode
Press Enter key to dene “Background Initialization”,
“Foreground Initialization” or “No Init (To Rescue Volume)”.
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 “Foreground Initialization”, the
initialization proceeds must be completed before the volume
set ready for system accesses. There is no initialization happed
when you select “No Init” option. “No Init“ is for customer to
rescue volume without losing data in the disk.
• Stripe Size
This parameter sets the size of the stripe written to each disk in
a RAID level 0, 1, 10, 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 cache stripe size.
• Cache Mode

as the card itself, must be assigned a unique SCSI ID number.
A SCSI channel can connect up to 15 devices. The SATA RAID
