We compared the GoFlex family and its various interfaces to some of the latest USB 3.0 storage devices.
Interface Performance
This chart shows the maximum throughput of the individual GoFlex interface choices. The USB 2.0 connections are limited to roughly 39 MB/s, which still is a modest result. FireWire 800 will take you to about 76 MB/s, and eSATA or USB 3.0 will unleash the full 2.5” hard drive bandwidth of 110 to 113 MB/s on the Ultra-portable models.
The desktop version could transfer 195 MB/s if the hard drives were fast enough. Keep in mind that this benchmark shows maximum interface throughput, not the throughput off or onto the physical drive.
