We got a new Mac Pro server and I am faced with cloning 4TB of data from one, to the other via. Firewire 800 cable and Target Disk Mode. Oh for Thunderbolt.
Is there an impact on the total speed of copying if you clone two hard disks simultaneously vs. cloning one hard disk, waiting for it to finish and then copying the next.
Total Time for: (old)Disk 1 -> (new)Disk 1 at the same time as (old)Disk 2 -> (new) Disk 2
Faster, slower or the same as:
Total Time for: (old)Disk 1 -> (new)Disk 1 THEN (old) Disk 2 -> (new) Disk 2.
Although this question would be appropriate for SuperUser, I'm asking specifically for our Mac environment. I think this is the type of thing that varies by operating system, and I'm not interested in the implications which are OS dependent (plus, I feel like this is my community, not SU).
