Now under AHCI management, I'm getting the full 500Mb/s.  Compared to the 250Mb/s I was getting before that this is a very good improvement.

Yes, you will see better benchmark results if the benchmarking program is mult-threaded (a good one would be).  If all you do is benchmarks, then AHCI is great.

However, you shouldn't see any improvement in file or program load time for "normal" PC use.

I'm not knocking AHCI.  I do believe that the OP should try turning it off to see if it resolves his problem.
