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. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet since 1994 www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike
