Choose from 32, 64 or 128 KB. The size selected affects how FastTrak sends and receives data blocks to and from the drives. In general, a larger block size is better when handling large data transfers (such as A/V editing and graphics) while a smaller size is better when handling email and other common server data. The default is 64KB. When in doubt, use the default value. 11.

This is the default. • Write Through - Slower but more secure. 12.
