IDE mode is when a SATA HD was emulate to run as an IDE HD @ easily understandable as PATA HD (older technology) compatibility mode.

In terms of performance, slower. But better integration with older hardware.

If you're using Windows XP, you cannot change this option, otherwise you won't be booting it at all. I haven't tried with other OS though.

If you wan to know whether you're running in what mode, you can find the answer here:

If you want to change it to AHCI (better utilizing your SATA HD), you can follow the instruction here:

or here (if you find the above sites difficult to grasp):

Well SATA HDD will perform like IDE if SATA drivers are not installed or the drivers are not available for your machine. IDE is the older technology which will give slow speed. If you currently have HDD on SATA mode and if you remove the driver or disable SATA Native Support from BIOS, the system will not recognize the HDD and OS will not book. Same is the case if you currently have IDE mode and you switch to SATA.
