USB 3.0 vs USB 2.0

[Woolyshark]

Hi Guys,

Wonder if anyone could answer me, but this is something I may consider if worth it.

I currently have a USB 2.0 motherboard as USB 3.0 is not yet completely feasible, so the next step is a USB 3.0 PCI Card.

Would it make any difference in speed and stability by connecting via USB 3.0 as opposed to using USB 2.0, using the Hauwai E367 modem?

Regards,

W.

Assuming the device you will be connecting with is also USB 3.0, the transfer speed will increase. Stability wise I would not expect anything different from 2.0.

Edit I see you mean with a modem, I would guess the modem is currently not saturating USB 2.0 so there should be no difference.

Short answer: No
Longer answer: Not much,more power on the port,higher theoretical Bus speed,which would again be bottlenecked by the PCI Bus speed - which is still higher than the maximum speed of your modem

I tried it & answer is no difference re modem
My angle for trying was USB2 is max 5V/500mA supply........USB3 is max 5V/900mA supply.
I run from express card USB3 to a USB3 powered hub & there is no differance from running off the USB2 powered hub.
I now know that power to the modem ain't a problem tho.

Say you had an external antenna mounting or a load of USB devices directly connected you could possibly have had disconnects due to lower-juice but in a 1 device scenario or powered you'd have 0 effect yeah

Thanks guys, so all said and done no need to shell out R250.00+ for the PCI card as yet.

No - but if you have speed/stability issues check out what your RSSI value is.
If that is good (-70dBm is better than -90dBm) then perhaps try a powered hub.
Alot of the time it can just come back to the network also.

I understand. So my main issue is that regardless of the USB type used, it will all be relative to the ISP, Modem etc. Well only until we get proper wireless data rates.
