USB 2.0, FireWire, Or eSATA: Which Interface Should You Use?
FireWire 400 on the G-Technology hard drive is faster, as it delivers roughly 40 MB/s read speeds and a bit more than 30 MB/s write speeds.
G-Technology G-Drive 1TB (FireWire 800)
FireWire 800 is even better with 80 MB/s read speeds and a bit more than 60 MB/s write speeds. The diagram also clearly shows that the drive’s performance decreases a bit as you get closer to the end of the medium.

The eSATA throughput diagram underscores how this interface is the only one that doesn’t pose a bottleneck to the hard drive. All other diagrams mainly display a horizontal line, while the eSATA diagram reveals the true performance of the hard drive that G-Technology uses.
