I currently do this, not due to problems, but to improve the write 
performance:

4xMaxtor 6E040L0  RAID0

UDMA133 -> 40M/s
UDMA100 -> 120M/s

(seem to find read performance is *slightly* slower for UDMA100, but not 
enough to make it worth worrying about).

However this may just be a quirk specific to my system (Tyan S2510 + 
PCD20271).

Cheers
