Any advice would be greatly appreciated.

Thanks for your quick reply.
The way adobe premiere works is that you need to have the program and the scratch disks on different controllers. Now im assuming that you can only have 1 raided hdd system in the computer (2 x 500Gb + 1Tb).
so to have the program on sata's i would not be able to use the raid, they would have to be seperate drives. If im wrong then correct me as it would be nice to have all sata's in the system.
Is there i big difference in the speed of the hdd's if it is raided?
As for the color of the dvd - lol, my bad :}

The gigabyte board does look good, as for the raid or mb going down, Thats why im getting the external hdd. I have one at the moment (40gb lol) all the inportant data will be stord on that drive.
the avi file size for 4 minutes of footage is 1 gb, hence the need for large drives and the raid.
So if i can get two raids, 1 system drive and 1 scratch drive that would be great.

Another quick question, are the raid system stable? If not then i may be best to keep the drive seperate.
