I had been reading about how AHCI mode makes the disk drives faster, especially SSD's but after I set Windows 7 to use AHCI and then changed it from IDE to AHCI in BIOS, I noticed immediately that programs like Chrome open a lot faster now, but on the other hand tranfer rates from my 2TB 7200rpm HDD onto the ssd have dropped considerably.

Why is this? Pls help!

EDIT: Battlefield 3 simply stopped working, it won't start anymore now.
