Use 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 cannot
be converted to "Dynamic Disk", because 4k sector size is not a standard format.
A single volume set is created and consumes all or a portion of the disk capacity available in this RAID
set. Define the capacity of volume set in the "Available Capacity" popup. The default value for the
volume set, which is 100% of the available capacity, is displayed in the selected capacity. Use the UP and
DOWN arrow key to set capacity of the volume set and press Enter key to accept this value. If the
volume set uses only part of the RAID set capacity, you can use the "Create Volume Set" option in the
main menu to define additional volume sets.
Stripe Size This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 1E, 10, 5, or 6
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.
Warning: Roaming the stripe size 256K/512K/1024K RAID Set to firmware version older than 1.52 will
cause data corruption.
A larger stripe size produces better-read performance, especially if your computer does mostly
sequential reads. However, if you are sure that your computer performs random reads more often,
select a smaller stripe size.
