ahci

I've formatted my notebook that has a 5400RPM HDD with ~500GB capacity.

After installing Windows 7 and about half the drivers (including chipset) I began to doubt whether to go for IDE or AHCI mode for my hard drive. There used to be a lot of discussion on the internet which is better and so far I understood it was particularly helpful on SSDs. Now the general consensus seems to be that AHCI mode is best for most hard drives. I have thus enabled AHCI in the middle of configuring my notebook (rest of the drivers, necessary software etc...)

Two questions:

considering my HDD's spec above, should I leave it on?
Is there any disadvantage of enabling it after Windows 7 and chipset drivers installation?

Windows 7 version is 64 bit Home Premium.
