My new build will be the first time I've used an SSD for my boot drive. In addition to the SSD (180GB), I plan to use a 4-disk RAID 10 configuration with WD Caviar Black 6 Gb/s drives. Before settling on the ASUS P8Z68 Deluxe MB, I want to be sure it will support this.
If you will be using Intel RST (Rapid Storage Technology) for the Raid 10, be sure to install the latest drivers/software from the Intel download site, since you have the Z68 chipset. Earlier versions have problems with z68.
I wouldn't recommend 'WD Caviar Black 6 Gb/s drive' since they lack TLER support. Instead Hitachi, Seagate, or Samsung which support their versions of TLER. There's no point in SATA3 Interface and simply look for 7200RPM and 16MB or larger cache.
