I recently got a new laptop (Dell Latitude E6410) which came with a regular hard drive. I removed the hard drive and installed Windows 7 64 bit fresh. I've been doing some reading about possibly changing a BIOS setting under SATA Operations. Currently it is set to "RAID On" but AHCI is also an option. Apparently I need to tweak the registry the reboot and flip to AHCI in order enable it.
My question is what exactly is it and why would I want to enable it? Will it provide faster performance with my SSD? Is this even necessary to switch to AHCI or should I leave the BIOS alone and stay with RAID On.
