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.
