That's not necessarily true. 4 drives on one card can completely
saturate a 33MHz/32 bit PCI bus. 4 drives @ 50 MB/s = 1.6Gbps. 4 of
those will saturate a 100MHz/64 bit bus.
Even if you aren't concerned about the performance you may run into
bus timeout problems. I investigated doing the same thing a couple
years ago, and read that lots of people that tried it and failed
because they kept getting PCI bus errors.
I ended up getting a 12 port 3ware card, and haven't had a single
problem. Plus, the 3ware cards support hot swap. I don't think the
standard SATA cards do.
