Select 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 MB).
The size selected affects how the PDC20319 SATA RAID Controller 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.
