Hi, I have an old macpro (2006) and am looking to upgrade to the new one. I have alot of internal HDs that will need to be moved to thunderbolt drives. My internal drives are currently backed up on NAS Seagate drives via a switch. I'm wondering if there is a thunderbolt drive that will connect to the new macpro AND connect to the network via the switch to be backed up on the NAS drives? thanks!!!
