And do you boot from it? I'm not the one to answer, but I'd like to highly recommend the 3ware=20 controllers (7506-xx). They are absolutely reliable if one drive fails, and they have been working= =20 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 st= ill=20 maintained. Also it's been the only controller which worked after pulling out the power= =20 plug of a drive, but I haven't tested the higher-end promise controllers (S= X)=20 although I'm convinced that they're not worth the money. No HighPoint or=20 SiliconImage based controller ever passed any reliability test for me.=20 Perhaps they are really mirroring, but if one drive fails (hard) you have n= o=20 working system. And of course you can boot a RAID5 set with the 3ware. It's recognized by t= he=20 ix86 as SCSI and the with the GENERIC kernel as twe.
