Hello there - first post! I'm transferring data from one Western Digital Firewire 800 drive to another (1TB bought 2008 and 3TB bought 2011, respectively), using a new (thin) iMac, which has no Firewire ports and two Thunderbolt ports. I want to know if it makes any difference which Firewire drive is closer to the computer. I'm using a Firewire to Thunderbolt adapter and the two Firewire drives are daisy chained. It's acceptably fast (about 3hrs for 500Gb) as I have it now: iMac - Drive A - Drive B; where A is copying to B. But would it be any faster if I swapped A and B around? What if I got a second Thunderbolt adapter for the second port on the iMac?
