Ok, so Ive had a MacBook Pro (MBP) now for about a year and love it. My friend has an older MacBook Air (MBA). Last night I noticed something a tad odd! We had all been on vacation together recently and I wanted to upload pictures from my MBP onto an external 250gig hard drive then upload to his MBA. I dragged the folder from my MBP onto the external drive (I had about 2.86gigs of photos) and it took what seemed like forever to transfer the files, it actually took about 10 minutes! When I unplugged it from the MBP and plugged into the MBA to transfer them over. It took less than 2 minutes to transfer them over? So what gives? Why does my MBP take longer to copy to and from a USB HD than an older MBA? Doesnt make sense, my MBP did have an overhaul a couple of months ago and i'm wondering if the tech chaps at the store replaced something in my MBP with an older part (not sure if it's possible but...) If anyone has any clues as to what's causing this id love to hear from you! Cheers PS I did try transferring data back and forth between my external hard drive and my MBP and I got the same really slow transfer rate.
