This is very boring... I thought USB 2.0 was supposed to be 480mb/s or something?

Iurrently transferring 500+gb of data from a usb hdd to my internal sata hdd and it's going to take all night.

Is there something I need to do to speed this up?

Thanks,

60Mb/sec is the theoretical maximum throughput before overheads. with overheads, its down to 53Mb/sec or so...in theory. In practice, you tend to get just under 2/3rd's of that, or 30-35Mb/sec in other words.
 
Yep. When I was putting all my stuf onto my external I actually got upto 40-50MB/s at some times when it was multiple files transfering
 
It goes something along the lines of how internet speeds works. We have fibre optic cables that can transfer insane amounts of information right now, but the actual speed depends mostly on how fast we can pump information through it and 'catch it' on the other side, in other words the stuff that's on either side takes precedence and determines to a large extent the end performance.

Likewise just because you have USB 2.0 or 3.0 doesn't automatically mean that your hard drives can use it to its fullest. This is the reason why some of the more thoughtful members disregard the current importance of fluffy new mobo features such as USB 3.0, unless that compatibility extends beyond the transfer interface to hard dives, usb devices, software etc. there is little point besides the hope of future gain.

i thought this thread would be about someone being amazed at getting a fast 30MB a sec through USB2 - lol. On all machines and drives I've used I only get about 20 at the most. It's usually 4-5 mins to transfer a 4GB iso.

However, in the case of USB3 it really does perform quite well.

For example:

Transfers are about 4x as fast, pretty much the limit of the HDD itself once the additional overheads of the USB interface are considered.

Again, a little slower than S-ata with the extra overheads but it's still quick; 200Mbyte/s over USB!

I must apologize, It seems I did not make it clear enough that what I meant was people buying a shiny new USB 3.0 mobo and expecting all their old hard drives, phones, cameras, ipods and whathaveyou to suddenly max out the latest interface.

But of course, just as you correctly pointed out, if one has the hardware up to the task USB 3.0 will and does make a pleasant difference indeed.
