How much data will be copied to the destination LUN?

A customer wants to reduce the performance impact incremental SAN Copy (ISC) has on their
source LUN. They plan to use a clone between the current source and destination LUN, and then
use the fractured clone as the new ISC source LUN. The source LUN performs four hundred 8 KB
random I/O per second, with a 3:1 read/write ratio.
The source LUN is 512 GB in size, and the clone will be fractured for five minutes.
