Why not just upgrade to 7-Stable and then use these:
they cost less than port multipliers. They don't do RAID, but then if
you're on 7-Stable, you can use ZFS zraid.

I had utter hell with a belkin pci sata card which used a silicon image
chipset. The main problem would show up when writing a large amount of
data to the drives which were in a zfs array. I even tried this card on
3 different motherboards with various combinations of sata hard disks
and the result was the same when writing a large amount of data, a drive
would randomly disconnect from the system. I understand from reading
sata controllers based on a promise chipset are much better under
In then end I trumped for a new motherboard with 6 sata ports on it and
it is running 6 x 500gb drives in a ZFS array just perfectly.
