RE: Switch from IDE to AHCI with new platform - Recommended!

Firstly, let me say that in terms of speed I have to revise my initial position. The scan time of my 2000 CDs music library during cMP start up is ~60 sec. in IDE mode and AHCI mode with "Integrated Peripherals/SATA Port0-3 Native Mode" Enabled and Disabled - equally! The initial difference that I reported was probably due to HD coming out of sleep mode.

Secondly, IRQs in IDE mode and AHCI modes are different from yours.
IDE with "Integrated Peripherals/SATA Port0-3 Native Mode" Disabled:




IDE with "Integrated Peripherals/SATA Port0-3 Native Mode" Enabled:




SATA with "Integrated Peripherals/SATA Port0-3 Native Mode" either Disabled or Enabled:




Therefore, given that I do not have IRQs conflicts like you (my non-onboard USB sockets are just for mouse/keyboard + seldom used service), my personal recommendation is to leave in SATA mode Enabled. :-)
