Recently my disk to disk transfer rates seem to have gone down the drain. Currently I have a 320gb Seagate 7200.10 as my boot drive and a 1tb WD10EADS as the storage drive. Whenever I transfer data to each other the transfer rate as reported by Win7 starts off normal at around 55MB/s but then it tanks to around 25-30 in a few seconds and remains at that speed for the rest of the file transfer. I know the estimated transfer rate shown by Win7 isn't all that accurate but I have even timed file transfers and they are indeed much slower than before. Is it possible that I've used an incorrect setting that would cause these slow transfer rates?
