A6. Hi-Speed USBs transfer speed is 480 Mbits/s (megabits per second), or 48 MB/s. Firewires transfer speed is 800 Mbits/s, or 80 MB/s. SATA II transfer speed is 3 Gbps (gigabits per second), or 300 MB/s. Because SATA II is nearly four times faster than Firewire and over six times faster than USB, it is the ideal interface for audio and video editing applications, high-end graphics, and all your other capacity hungry applications that demand continuous high performance throughput.
