Would those drives be attached to a Silicon Image (SII) SATA controller? A Highpoint? I found in testing about 2 years ago that under Linux (looks like you're BSD), most SATA controllers other than the Intel PIIX are horribly broken from a performance standpoint, probably due to bad drivers but I'm not sure. Now I think whatever is commonly used by Nforce 4 implementations seems to work ok, but we don't count on them for RAID configurations yet. - Luke
