Hard drives are not my specialization but I just got a new mobo the ASUS P5LD2 and it supports SATA Had drives and has a RAID controller. So I was planing to get to Seagate Barracuda 7200.9 80GB 3.5" SATA 3.0Gb/s Hard Drives and putting them on RAID0. Now my question is if SATA 150 is completle different and Cant be used and Vica Versa with SATA 3.0gb/s ???
