Note:
RAID level 3 and 30 can’t modify the cache strip size.
- 4K Block
It changes the sector size from default 512 bytes to 4k bytes.
The maximum volume capacity is up to 16TB. This option works
under Windows platform only. And it can not be converted to
“Dynamic Disk”, because 4k sector size is not a standard format.

• Initialization Mode
This option is used to define “Background Initialization”, “Fore-
ground 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 happened
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 0, 1, 10, 5, 6, 50 or 60 logical drive. You can set the
stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256KB,
512KB, or 1024KB. A larger stripe size produces better read
performance, especially if your computer does mostly sequential
reads. However, if you are sure that your computer does ran-
dom reads more often, select a smaller stripe size.
• Cache Mode
The 6Gb/s SATA RAID controller supports “Write Through” and
“Write Back” cache.
