I ran the tiobench test on -CURRENT a few days ago and the ahci driver

I was running the AHCI driver on the freebsd-current tinderbox for 3
weeks with very good results. I had to recently change back to the
ata code as smartmontools are not (yet) supported and one of the
drives started to throw errors. Other than that, I found it to be the
same speed or faster (depending on the workload). This was on a
Phenom 9950 Processor and ATI IXP700/800 SATA300 chipset on AMD64, 8G of RAM.
