I was trying to copy a video over, and it was just really slow under 1mb/s is this normal?

What OS are you using on your computer?

Windows likes to run your 2.0+ USB at 1.0 speeds often times. Usually just installing the newest drivers will help that.

Or is there a possibility that you only have USB 1.0?

Windows 7 64 bit

were you trying to copy to phone memory or micro sd card?
if you useing sd card and it is slow that is what you going to get
class 6 gives me around 8MB/s
some fake hardly makes 800KB/s

i'm on win7 x64 as well so it isn't win7 problem

copying to memory

Copying to memory, but other devices work fine through that port.

I had a similar issue the other day with a Vista machine and found that the desktop in question was merrily virus scanning my N900 in the background. Once it had finished that things perked up quite a bit. Could that be something similar here?

Data transfer is really slow if you have two or more operations running simultaneously. A virus scan is likely cause if you're not manually xfering multiple files simultaneously.

Why is it that if you try and copy 2 things simultaneously the transfer rate drops to a ridiculously low rate?

(If you are doing 1 copy job I get around 13mb/s average)
