I have been using 7 since the 6000 builds. I just started using the RC1, and the data transfer rate is stupid slow. I can't get USB 2.0 above 19 MB/s and I can't get drive to drive above 10 MB/s! The fact that my USB is going faster than my two harddrives is absolutely rediculas. I have seen this was a problem in Vista, but has anyone found a fix. Sorry if this is a repeat. I did a search, but I didn't find any other posts like this.
