My current set up is a 2009 iMac with two external drives connected via FireWire 800. One of the drives stores all the "home" folders with pictures, music and movies while the other one is a Time Machine back up. This iMac is being replaced with a new one that is expected here in the next two weeks. I really like my external drives (OWC Mercury Elite Pro) and would love to keep them in their current rolls. These drives have a variety of inputs (USB 2.0, FireWire 800, FireWire 400, eSATA) so I've got some options. My question is, what is the best way to go from my new iMac's Thunderbolt to these drives? The cheapest solution is probably a Thunderbolt to Firewire adapter. Of course my drives also have eSATA ports, so I could do Thunderbolt to a LaCie eSATA hub and then out to my drives. Of course that's more of an expense. If all I'm doing is accessing home folder stuff and doing back ups, what's the best bang for my buck?
