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

Find Model Number & Serial Number Of PC From Command Line

Here is a very simple script to return model and serial number information for your computer.

To retrieve serial number of the computer run the following command from command line

wmic bios get serialnumber

To retrieve model name of the computer run the following command from command line

wmic csproduct get name

This code doesn’t return information for all computers, but I’ve found it very usefull where its available.
