What's the main difference between rev. 1.0 and 1.1 because i can buy the 1.0 here in the netherlands (mobo is only thing i need to finish my rig )

And i have 3 disks, 2x Raptors 74GB and 1x 36GB Raptor, if i would like to run Raid0 on the 74GB disks i want to use the ICH9 for it and should i use the ICH9 also for the single 36GB disk or is it better to use je JMicron next to the Raid0 on the ICH9?

Tips are welcome...
