In case anyone was interested in the 8 port supermicro card:

http://www.newegg.com/Product/Product.aspx?Item=N82E16815121009

I did some tests on it with software raid (mdadm). So far the results were very respectful (in my opinion). Here are the results of raw sequential read/writes in raid0, raid10, raid5 and raid6 and actually performed better in software raid than a 3ware 9650se. All testing was done on a core 2 quad CPU system with the controller in a PCI-X slot hooked up to 8 seagate 750 GB 7200 RPM ES.2 series hard-drives.

Here are my results:

Its' an incredible performer for the price and it's features (ports).

I would die and go to heaven if Supermicro made the next generation of this card but PCIE and give it MiniSAS headers for tidy cables.

LOL, I agree, it would be very usable in my backup server, among others!
 
These Supermicro cards are great.

I dunno about PCIe I kinda like it being PCI/PCI-x compatible. But definately MiniSAS headers would be sweet.

EDIT: well if it were pcie x1 I would like that cause so many desktop boards have x1 slots and it seems that nothing useful actually uses x1 slots.

PCIE devices are backwards compatible in most cases to x1 or whatever lower slot that you have, so yes, that would make use of the useless x1 slots :)
