Here's a question for you all. I've just copied a 12gb folder from my a memory card to the desktop of a Mac Pro, and it took about 15 minutes or so. I then dragged a different 6gb folder on to the same memory card from the Mac Pro, so I could transfer it to my new MBA. However, copying that smaller 6gb folder from the card to the MBA is currently giving me an estimated time of 'about an hour'. Is there any reason obvious reason I'm missing why copying from the card to the Pro took 15 minutes to copy 12gb, but copying from the same card to the MBA is taking an hour for a folder half the size?!
