I'm using Microsoft's imagex.exe for backup and restore in 2 configurations: A mirror raid of 2 500GB hard drives, and a mirror raid of 2 1TB hard drives. The second configuration is 30% slower even though in both configurations the number of files and their size is about the same.
My question are:
What are the parameters that effect the speed of Microsoft's imagex.exe in general?
Would a 1TB hard drive be slower than 500GB hard drive, even though they both contain the same amount of data?
