IDE is an old standard . Original IDE hard drives had huge flat ribbon cables with 40 , and then 80 wires .
When SATA got introduced operating systems didnt have built in SATA drivers so board makers included the IDE mode
Use AHCI and NCQ and enable SMART for your OS
thank you for this, i'll use AHCI, could you please tell me what SMART is and is this enabled via BIOS or when i install Windows 7?
