Selecting Stripe Block
For RAID 0 Striped arrays only, you may manually select the “stripe block size.”
Use the Spacebar to scroll through choices progressing as follows (1, 2, 4, 8 ,
16 . . . 1024).
The size selected affects how FastTrak100 sends and retrieves data blocks 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.
