Anyway, I shelled out for the Escalade controller which should be well-supported by any BSD and of course Linux, and also quite fast (real hardware RAID, presumably not just a BIOS to boot a software RAID volume like the other controllers). I still doubt this array will have the speed of my 10K RPM SCSI mirror, but should be close enough. It's a shame for this price it doesn't have cache. There is an interesting SATA vs. SCSI benchmark shootout at tomshardware.com.
