oldschool desktop 32bit 33Mhz parallel PCI  will be a performance 
bottleneck for more than 1 SATA drive.

Is your server PCI 32bit, PCI 64bit, or PCI-X (64bit, 100-133Mhz), or is 
it PCI-Express and if so does it have x4 or faster slots?

As someone else said, a SATA card likely will NOT be bootable, unless it 
has a boot eeprom on it, and these cost more.
