Hi everybody - I have an ASUS P6T Deluxe V2 mobo running 3x1TB drives. Two of the drives are WD Black (7200 RPM) and one is a Seagate Barracuda (7200 RPM).

I have noticed that my 2nd and 3rd drive (basically D: and E:) throughput is much lower than my primary drive (C:).

The thing is that my "C:" drive and "D:" drive have the same specs (WD). If I move a file from either D: or E: ro C: I get an average of 70-80 mb/sec, if I move from any drive to either D: or E: I get 25MB average (which is WAY low).

I checked indexing and it is disbaled. What else could be causing this? Any thoughts or suggestions?
