> first file is written fast and at the second is a short delay I've noticed that with USBs as well. File writing speed (when copying large amounts of data) seems to start slow, peak out a few minutes in, then drop, and stay somewhere in between for the remainder of the time. Does anyone know why this happens? Is this how USBs work?
One more question for OP- why are you doing this? Copying your entire / to another drive? Backing up? Or what?
