A while ago, I bought a 4GB usb pen from ebay to replace my 512mb one. Now, I guess the fact that "bought" and "ebay" doesn't go well but I suppose I just couldn't be bothered going to my local electrical store and paying the little bit more, and I regret it. I tried putting in a 50mb file and it took absolutely AGES to complete but before I consign this to "I got ripped off pile" what are the factors that can make the transfer speed go quickly when I'm copying stuff over to it? Or was the chances that the reason the pen was slow was that even though it had a high capacity, the speed wasn't.
