Ok, WTF?
I just built a brand new Sandy Bridge i5 2500k system with Windows 7 Home Premium on the C:\ (SSD). I have another SSD, D:\ from which I'm trying to copy about 7GB of files onto a 250GB WD 7200 Caviar SATA drive. At first, I dragged about 2GB worth of files from the SSD and it quoted me a transfer time of 2+ hours. I then dragged another 5GB of files from the same SSD, to the same destination HDD, and it said 10 minutes.
After a couple of minutes, speeds on both transfers had stabilized down WELL under 1MB/sec, with a completion time in excess of 11 hours. CPU load is 1%, memory ~30% (total 8GB). HD Tune benchmark on the HDD gives an average transfer rate of 55MB/sec.
What is going on?
