Meaning support for the U/66 is raw. Ultra/33 is solid and as fast as
intel's PIIX4E chipset.

All true, but these are commercial production issues. No crash, but
have to power down to replace drives (except for commercial EIDE hot
swap. Bigger $$ but not as much as SCSI).
I've run both a 2+2 RAID0 and RAID0+1 on a single U/33 with great
results.
2+2 RAID0: hde+hdg = set 1, hdf+hdh = set 2. Performance was 2x single
disk.
RAID0+1: hde+hdg = stripe set 1, mirrored to hdf+hdh.
RAID5: hde+hdg+hdf+hdh
Or use 2nd U/33 or mix U/33 with onboard: hdc+hde+hdg, hdd+hdf+hdh
Buy big, fast EIDE.

Yes, but start with 4 on 1 controller. Difference will not be
measurable.
