Hello all,

Well when i built my PC i didn't know about the AHCI for sata HDD DVD so my system is set to IDE , Was wondering how much of a differences it makes, Also If i do reinstall one day could i download the drivers off gigabytes website to a USB drive and use that over a floppy after i hit F6 on the install. When i do reinstall i will add a 120 gigs SSD for my OS and program's and use my WD black 640 for a storage drive.


Thanks

I've got AHCI installed on my 80gb SSD. It makes a difference, but its not huge. I think the difference is even less for HDD's. Plus, when you enable it after you've installed windows, it is known to be problematic.

Thanks for the reply. I was not going to try to enable it now i was going to do it next time i reinstall windows 7 when i upgrade to a SSD. My question is do i have to install drivers for it when installing windows 7 or does windows 7 have drivers for it and if i need to install a driver can i use a USB flash drive over the floppy.

Thanks

Windows 7 has the drivers for pretty much all of the popular SATA chipsets available when it was released. It's pretty unlikely that you'll need to do anything special unless you're using a *really* new motherboard, perhaps one that supports SATA Version 3, for example.

My guess is that the driver would be for Windows XP which doesn't include native support for AHCI.

If the motherboard has the option, then the motherboard supports it. Take a look and see.
Windows Vista and Windows 7 have support for it. XP does not. If you have vista or 7, there won't be any drivers you need to install, just enable it on your motherboard
