Which is faster USB or Ethernet ?

[GuRu]

Reading all the different problems ppl have been having and the results they have achieved after finding the sweet spot etc. it seems that some are getting faster speeds / stability using USB.
If so post comments here and maybe a poll could be started.

Usb1 or 2? I have a 40g USB drive that takes forever to copy on my old pc, but a breeze on a new. In that case I'd believe anything is faster than usb1 (except telkom "broadband")
Anycase, TotalCopy gives me around 666kb/s on usb1, but about 5000kb/s on my LAN...
HTH

All depends on the USB and ethernet connection speeds. USB v1 is only like 2mbits/sec where as USB v2 is 480mbits. Same with ethernet is it 10mbit 100 mbit or 1gbit?

If your speaking in terms of latency i have no idea which is faster i'm afraid, but i'd put my bets on ethernet out performing USB.

My experience, if everything set up right, the two are identical (that is USB2 vs 10 Mbit Ether - UTD only does 10)

i find the Ethernet allot faster and more reliable, i think there may be issues with the drivers.

fact is as long as your pc can handle the usb overhead, which most pcs can, then they are the same speed

USB 1.1 runs at a maximum bus speed of 12mb/s which is faaaar more than enough to handle the 1mb/s communications between your PC and the UTD. Latency on USB is negligble, depending on how much of the bus bandwidth is being eaten by other devices. So unless you have a set of USB speakers or some other USB hungry devices on the same controller, I can't see USB being slower than the Ethernet on a pure transmission level.

The only issue that could affect USB versus Ethernet reliability, and performance, is how well each of these stacks are implemented in the UTD. If the UTD USB PPPoE stack is poorly designed, it may affect the communications detrimentally. Likewise the case for the Ethernet stack.

However badly either of these two stacks may be implemented within the UTD - unless they drop frames at 1mbp/s rates - there is little chance that there will be much difference in performance between the two, that is directly related to the actual UTD <-> PC connection layer. If there are issues it might be due to the performance of the actual stack on the UTD.

To all that replied thank you.
I guess i will leave my UTD via ethernet up on a pole for a while longer or until i can test an external antenna.

im sure i had this argument with you a few months back and you were adamant that ethernet was they way to go

 

[slimothy]

really, well thats funny because i use usb basically all the time, i think what i said months ago is that ethernet is more efficent when it comes to memory because it uses dedicated hardware and therefor there is no overhead, but this overhead on your average p4 4ghz is extremly tiny

 

[lilgindauk]

depends on your system. usb seems less stable but has a faster flow rate

OMG

 

[slimothy]

yeah lil g you're talking out your arse

 

[lilgindauk]

then why up there he said usb 2 is 480mbits and ethernet is 100mbit??????

 

[slimothy]

usb isn't less stable and you get gbit ethernet cards as well

 

[guest2013-1]

also remember, he runs his ethernet from the pole he has his UTD on, with USB, the longer the cable the more the signal degrades, wheras with ethernet you can run a 100m cable with almost no loss.

 

[slimothy]

oh i seriously doubt that,

 

[ic]

USB has a max cable length of 5m before it starts degrading massively, however you could have a USB hub every 5m to amplify or whatever, but no one in their right mind would bother when you can use a single 100m long cat5 cable instead...

 

[slimothy]

yeah i'm not sure who would opt for a long usb cable, so how much degradation accurs per 5 meters? is it a time thing, that is to say latency or is is a speed thing, and how much

+usb +cable ~degradation
