What interface has the highest transfer rate?

[ablang]

Which interface's most recently approved specification calls for the highest transfer rate?

a. USB
b. SCSI
c. Fibre Channel
d. IEEE-1394 (Firewire)

[qball]

Is this a trick question?

It is not USB (1.0 or 2.0). USB2 is around 150mbps...

The new SCSI160 will do 160Mbps.

Lastly there exist IEEE-1394 at 400Mbps, faster speeds being developed.

Yup, Firewire definetely lives up to its name.. http://sysopt.earthweb.com/forum/smile.gif

Heres a question, If firewire is so much faster than these blasted IDE cables, why isnt everything inside my computer hooked up using firewire??

[Warthog]

IDE was adopted as standard so major companies made it in their systems. Firewire came along and was ignored because it was too risky to use something "non-standard"

Same story: Zip 100 vs. LS120
Sorta same story: Zip 250 vs. CD-RW

In each story, their is an obvious one that you would pick because it is better: Firewire, LS120, CD-RW. But the "inferior" product is still supported by major suppliers, etc. so it is still bought by the public.

Do you understand what I'm saying at all?

The Mac's made a major move to support firewire early this year. Their Powerbooks actually dropped the SCSI connector all together in favor of a firewire port(s).

Firewire isn't really all that fast as of yet. 400Mb/s is around 50MB/s. It's basically a fast USB connection and it's convenient usb features are what makes it attractive for manufactures to implement.

I think the performance of firewire and fibre channel standards are being confused with each other...

your correct about 400Mbits/s of the current IEEE 1394 standard. -the enhanced standard calls for up to 800Mb/s and a newer proposed version of it is just past to a gigabit-

But the SCSI160 is actually 160MBytes per second, which is over a 1200Mb/s.


The (performance) requirements given to the fibre channel standards group, calls for speeds from 266 megabits/second to over four gigabits/second. Currently, they give us reliable gigabit performance. With 2gigabit speeds on the horizon.

I just got a firewire card for my digital camcorder. What else can I use it for?

[chipbgt]

right now, I think thats about all they are used for. Like mentioned, it hasnt been ported over into anything else yet.

[ablang]

I think Edge got it.

It's Fibre Channel. 1.0625 Gigabaud or 200 MBps in full-duplex mode.

SCSI-2 is 80 MBps.
