What speeds do the various devices run at? (USB / SCSI / LAN etc.)

Network / USB / SCSI – speeds.

If like me you’ve started to get a little lost in all the various network, cabling and WiFi options you might be interested in this short comparison of the various cable types.

Cable Type – Speed

USB 1: 1.5 Mb/s - 12 Mbs
USB 2: 480 Mb/s
Firewire 1: 100-400 Mb/s
Firewire 2: 400-1200 Mb/s

Ethernet / Network

10BaseT: 10 Mbs
100BaseT: 100 Mbs
Gigabit: 1000 Mbs
Wifi
802.11 2 Mbs
802.11a 54 Mbs "upto" First standard
802.11b 5.5 & 11 Mbs "upto" Most common
802.11g 54 Mbs "upto" Not yet standardised
Bluetooth 1 Mbs "upto"
Modem .052 Mbs
ISDN .064 Mbs
ADSL .5 - 2 Mbs download, 0.256 Mbs upload
T1 1.5 Mbs
T3 = 28 T1 lines!

Just for interest, here are assorted SCSI and IDE speeds too:

SCSI-1 5 Mbs
SCSI-2 10 Mbs
SCSI-3/Ultra 20 Mbs
Ultra2 40 Mbs
Fast Wide 20 Mbs
Ultra Wide 40 Mbs
Ultra2 Wide 80 Mbs
Ultra 160 160 Mbs
ATA/EIDE 133 Mbs
Serial ATA 150 Mbs

Now I know there are all sorts of variables in these speeds, but these do give you a baseline comparison.
