Intel's documentation states that it only supports SATA II (3.0Gb/S), so you won't be able to max out the better SSD's, which are SATA III (6.0Gb/S). Sustained read/write speeds of the top tier SSD's can do 500MB/S, but SATA II will cap you at half that, about 250. You'll still notice an appreciable boost in boot up/shut down and launching apps, even with SATA II (I'm stuck with that too).
Another thing you might want to check is if your specific motherboard has AHCI as an option in your BIOS. This depends on the manufacturer. This provides support for TRIM, which is important for the SSD's longevity.
One option to solve both problems is to get a SATA III controller add on card. You'll be capped at 5Gb/s since it's on a PCIe...
