There's one at :īut even this leaves some question, as perhaps their specific USB 3.0 implementation is not optimal. Theoretical maximum and real-world speeds can vary wildly, and only some significant actual testing will give meaningful answers. Intel Thunderbolt, as per the Wikipedia SATA link just above, is 10Gbit/s.Īlso, none of these answers so far give any practical/useful information. When considering throughput the list looks entirely different.įor the speed/throughput/bandwidth of more devices have look at this article on wikipedia

USB 2.0 sends command and control data through the same connection the data uses limiting the 480 Mbps connection to 380 to 400 Mbps. The entire 400 Mbps is available for data transfer. As an example, FireWire 400 is a serial connection. However, this does not provide the actual answer. Thunderbolt = 1.25 GB/s × 2 (2 channels).Thunderbolt = 10 Gbit/s × 2 (2 channels).eSATA = Up to 6 Gbit/s (750 MB/s) right now as it depend on the internal SATA chip.
