If you check the reviews, a guy that works for Buffalo clearly states that the bottleneck is the HD itself, that will operate at 100-120 MB/s at best. Assuming the best case scenario of 120 MB/s, the transfer speed is only 960 Mbps, about one tenth of Thunderbolt's rated 10,000 Mbps.

The one thunderbolt port is killing me, I would love to have an option that allowed daisy chaining. Still, it's good to see the price drop for these thunderbolt devices.
