Afaik the Perc 5/i and /e are more or less rebranded LSI-cards (they're
not identical in layout etc), so it would be a bit weird if they
performed much less than the similar LSI's wouldn't you think?
And as far as I can remember, our Perc 5/e actually performed similar to
a LSI with similar specs (external sas, 256MB ram, etc) we had at the
time of testing.
Areca may be the fastest around right now, but if you'd like to get it
all from one supplier, its not too bad to be stuck with Dell's perc 5 or
6 series.
