Have you enabled the high speed USB controller in the BIOS?
bigger the capacity, slower the transfer rate for solid state
that's why there's dual channel flash cards now
Have you also tried plugging it into a port on the back? The only thing I can think of that would cause a really noticable slow down would be if it's not actually on a USB2 port. I suppose the files could be small enough that it doesn't have time to get up to full speed as well, but I'm assuming you are transfering big enough files.Yes, It's enabled.
Sorry for the late reply, excuse my bad memory I forgot about this thread.
