I have 2 SATA SEGATE harddrive one 80gb and other 120gb. I just upgraded my system to AMD64 3500 and mobo A8V-E deluxe. I've ran some benchmark utility and it tells me that max transfer on my 80gb is 53mb/s and my 120gb came up with 3 mb/s. I've noticed that my whole system lags when i'm saving large files. Installing and decompressing take forever too. Can you guys tell me what could be wrong with my system. I have xp pro. On my mobo all setting for my sata drives are auto, and there is nothing else to set up.
