Selecting Stripe Block
For RAID 0 and RAID 0+1 arrays you may manually select the stripe block size.
Press the Spacebar to scroll through choices progressing as follows (16, 32, 64,
128, 256 MB).
The size selected affects how FastTrak TX4000 sends and retrieves data blocks
to and from the drives. You will need to perform your own testing to determine
how the data block size is affecting your particular use of the array. In general, a
larger block size is better when handling large data transfers (such as in A/V
editing or graphics) while a smaller block size is better when handling e-mail and
other common server data. The default is 64K.
