how to install amd sata ahci controller driver

* All of the benchmarks I posted above are using the default 'Balanced' power option in Windows 7.

Also got rid of any intermittent sleep problems, particularly the common one with the MS AHCI driver and bigger drives (I have two 1TB drives as storage) which don't power up as quick.

I do notice that things are quicker and more responsive with the AMD which I believe is down to lower CPU usage*. I haven't noticed any boot delays with either driver if I'm honest. The board I use now POSTs in a second or so and is a nice change. My old Gigabyte board did have a long POST time (about 6 seconds or so). RAID supports SATA controllers, and many RAID products enable AHCI upon installation to provide advanced storage features for single-disk applications. I'm using a GA-870A-UD3 now, which has the SB850 chipset. I noticed you use a Gigabyte board as well, Gigabyte's AMD boards have a long POST time and there's no way to disable the Gigabyte RAID bios so it always loads up and adds a few seconds to boot times. I have noticed in the past however that I get less of a boot delay using AMD AHCI drivers on my 790FX chipset (I get about two or three seconds of boot delay after POST occurs where the SSD or hard drive isnt showing activity, when I tried the AMD AHCI driver sometime in the middle of last year with a different hard drive, that boot delay went away). I probably won't be changing to the AMD driver until next time I do a clean install though as the MS driver is working perfectly for me.

Looks like the AMD driver is now finally at least on par with the MS driver.
