I've read some years-old posts that say you should tweak some options in Windows to get the best performance. But then I read that this is no longer necessary with today's SSDs.
I installed a new Corsair Force GS (360GB) SSD to replace my existing HDD. It claims read/write of 555/530MB/s. Here is what I'm getting:
CrystalDiskMark Results - Initial Run
CrystalDiskMark Results - After BIOS Update
CrystalDiskMark Results - After Driver Updates (All out-dated drivers including AMD RAID and Chipset drivers.)
AS SSD Benchmark - After Driver Updates
Winsat Results - Initial Run

Note: This was not a clean install of Windows 7. I copied the partitions from my original HDD to the new SSD and then used GParted to align the first partition (System Reserved) to 1MB/MiB.
So, what's the scoop? Can I do anything to squeeze top performance out of my new SSD?
