I have searched the forums, but all related topics seem to be inconclusive or not applicable. I just finished copying 2gb of files from my macbook to a Lexar 8gb flash drive. It took about 12 minutes. I then immediately ejected the drive, inserted it into my iMac, and copied the files over, it took a little over 2 minutes. A 700mb file being transferred right now from my macbook to a different Sandisk flash drive. It took about 3 minutes. This rules out the peripherals right? All speeds where from a direct connection of drive and usb port (no hubs). So why is my macbook so slow transferring over usb?
