Well I was going to point you to How to know if hard drive supports Sata3 (6Gb/s) but your question is not what Sata version is supported but if the 400 you are seeing are in fact Sata3. TIPS WHEN SELECTING A GREAT SSD DRIVE I actually made a benchmark test with 3 hard drives on the same motherboard found here in Spanish and the things I learned from it ...
