The bandwidth of SATA 3 is 6 gb/s but the bandwidth practically supported is 600 – 1000MB/Sec (depending on chipset). Similarly, for USB 3.0 is, 5 Gb/s , with practical throughput of 640mbps.

In both cases, its the device which gets maxed out while reading or writing is usually the slower one. Even if you have a fast external USB 3.0 but your internal HDD cant read that fast, your overall bandwidth would be limited. You can only transfer what you can read practically. To get maximum benefit of both USB 3.x and SATA, both the drives must have have read and write speeds of equal range, eg: if internal reads data at 500 mb/sec and external can write at 500 mb/sec, you now have maxed out the “system” bandwidth.

Tune Pro Sata 6 is faster than USB 3

Thunderbolt

Mit My Book Thunderbolt Duo eröffnet sich in puncto Leistung eine völlig neue Dimension. In der Welt der HD-Videobearbeiter und anderer kreativer Profis herrscht immer Termindruck. Bei diesem Laufwerk mit seinen erstaunlichen Datentransferraten von bis zu 300 MB/s* bleibt Ihre Kreativität immer in Bewegung. Endlich ein Laufwerk, das mit Ihrer Kreativität Schritt hält.

*300 MB/s lässt sich durch ein einzelnes System erreichen. Mit Anschlussmöglichkeiten für zwei oder mehr Systeme, um Übertragungsraten von über 600 MB/s zu erreichen. Die angegebenen Transferraten gelten für das 8-TB-Modell im RAID-0-Modus.
