I know with older promise controllers, it wasn't possible to run more
than 2 in one system as far as I remember due to some dma issues.  Not
sure if that applies to the SX8.

If it turns out the SX8 has issues (like the one pointed out earlier
about number of commands to the card at once) or that it can't have 3
cards in one system at once, then what?  Are you then out $540 + the
cost of a better controller?  Certainly worth finding out before
spending the money.

Of course those aren't hardware, and are only meant for small toy raids
for windows users.  The rest of use treat them as ide/sata controllers
only.  I haven't seen one of those with more than 4 ports either.  If
the SX8 is one, then I must admit I haven't looked at it before.  I try
to avoid hardware from promise whenever possible.
