Or perhaps I didn't make myself clear. I have two 80GB WD Special Edition drives. I am Mirroring them together. When I mention having things on seperate drives I was refering to my SQL databases and web pages and such each on thier own drives (money permitting also raided to other drives.) But no right now I am looking at installing everything on one drive. I have actually already done it wil no problems so far. The system is using the ro0 driver and I think I am good to go. I wasn't sure if there were optimizations I should be aware of or utilities or anything. This is my first drive set ever. So I am looking for any tips. The block sizes question seems to only apply to a striped drives. It was a seperate question and even a seperate thought all together.
