Today I wanted to move some files over from my laptop onto my desktop (about 4 GB). I was going to whip out my trusty thumb drive but I thought why not just use my 1520. I have a 128 GB SD card so I have plenty space for it. I dragged the files over to the SD card in 1520 and everything seemed fine but when I plugged it into the desktop to take the files off the process was painfully slow. I ended up stopping the process and plugging the 1520 back into the laptop and tried to copy them back again to confirm it was the 1520 and not my desktop and it was super slow again. Both my laptop and desktop are running windows 7 64bit. Am I the only running into this issue? Anything I can do to speed this uo because it would be awesome to use my 1520 to move files on the go considering I always have it with me.
