If your monther board  built in PCI-E slot,  you may plug this card into it.Then you can get 2 SATAII ports and 1 IDE port. PCI-E slot is faster then regular PCI slot.
( PCI Express, PCIe, or PCI-I (not to be mistaken for PCI-X) is an implementation of the PCI computer bus that uses existing PCI programming concepts, but bases it on a completely different and much faster serial physical-layer communications protocol. PCI Express was formerly known as Arapaho or 3GIO for 3rd Generation I/O. PCIe transfers data at 250 MB/s per lane to a maximum of 32 lanes, a total combined transfer rate of 8 GB/s. It must be noted that PCIe is able to transfer data in both directions at once (full-duplex). This effectively doubles the data transfer rate allowing 500 MB/s per lane giving a total combined transfer rate of 16 GB/s when 32 lanes are employed.)
