And do you boot from it? I'm not the one to answer, but I'd like to highly recommend the 3ware controllers (7506-xx). They are absolutely reliable if one drive fails, and they have been working like a charm (including the 3dm disk manager) for me up to FreeBSD 4.6. I don't know about 3dm and newer versions but the twe driver seems to be still maintained. Also it's been the only controller which worked after pulling out the power plug of a drive, but I haven't tested the higher-end promise controllers (SX) although I'm convinced that they're not worth the money. No HighPoint or SiliconImage based controller ever passed any reliability test for me. Perhaps they are really mirroring, but if one drive fails (hard) you have no working system. And of course you can boot a RAID5 set with the 3ware. It's recognized by the ix86 as SCSI and the with the GENERIC kernel as twe.
