Why is the internal HDD listed twice in the chart with the same interface?
Also, people should be aware that these throughput numbers are the best you'll ever get; that is, sequential read and write with a relatively large file when the drives are empty. Try filling the disks 75% full and then do a random read or write with a bunch of 1MB files - the numbers will drop drastically. Part of the reason is because as the drive fills up, the heads move toward the inner tracks of the platters where distance covered for the same angular velocity is lower, thus transfer rates drop.
Thunderbolt is a fast interface, but I still prefer a NAS device because I can access it from other computers and devices on my network.
