How Fast Is A USB Connection?

Data transfer speed table

USB 1.0:	> 2 MPPS
USB 2.0 FULL SPEED:	12 MBPS
USB 2.0 HIGH SPEED:	180 MBPS
FIREWIRE-400:	400 MBPS
FIREWIRE-800:	800 MBPS
ENTERNET [10BASE-T]:	10 MBPS
FAST ETHERNET [100BASE-T]:	100 MBPS
GIGABIT ETHERNET [1000BASE-X]:	1000 MBPS
ATA-133:	1064 MBPS
SATA-150:	1200 MBPS

NOTE: these are rough speeds that may be possible.

The typical sustained transfer rate will be lower. Data rate is also dependent on the system architecture, the PCI bus and the attached USB devices
