both results are VERY low. for example 4 raid0 drives should easily reach 140mb/s, as
i've seen an Elite 1600 run on a Tyan dual athlon board.

I see, then my initial suspision that the problem could be related to AMD is not \
true.

Atleast the problem is definetly related with PERC cards, since the original LSI ones \
work fine.

I won't flash the LSI bios unless i hear from someone who has already done it, 20mb/s \
writes is better than 0mb/s ;)
