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

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.
