- Just how fast is that device? -

 

Each device has a specific data transfer rate that is either MBps (Megabytes per second), or Kbps (kilobits per second).
The following chart shows the maximum that these device can go with the correct cable attached:
 
 
  DEVICE    SPEED
ATA / IDE / EIDE / DMA / UDMA 16MBps to 33MBps
FireWire 480MBps
Parallel Port 115Kbps
Serial Port 115KbBps
SCSI Interface 80MBps to 640MBps
USB 1.1 12MBps
USB 2.0 480MBps
802.11b 11MBps  @ 2.4Gigahertz
802.11a 54MBps  @ 5Gigahertz
802.11g 54MBps  @ 2.4Gigahertz
