My 1TB Cav Greens come in at 105 read. My 5 year old Seagate 7200.10 320 hits 75-80 read. A new Black like that should be about 130-150 like my 320gb Samsung F4.. A driver update might help, but I wouldn't count on it. It is worth a shot though. I'm using the stock Windows SATA drivers to get those speeds. I haven't noticed that much difference between the later Intel drivers and the one built into Windows 7 personally, but mine are on Gigabyte boards not Asus boards. I do have AHCI enabled though. I prefer to manually install the drivers from the F6 Floppy Disk Zip
file rather than using the installer for the SATA drivers. I don't like having the rapid storage manager software running in the background wasting resources and cpu cycles. You don't have to install them using the F6 method during the Windows Install. I install them manually from Device Manager.
