Making different partitions wouldn't really be advantageous because it's all going to one logical device anyway. It would be OK to put everything on that one partition. Raid 5 is a fine middle-of-the-road solution as far as speed and fault tolerance go. If you were more concerned with speed, you might want to switch it to raid 0 (striping without parity) and create seperate logical drives for your data and logs (*Make very sure you're getting good backups if you do this*). If you're more concerned with fault tolerance, you may want to go with raid 1 (mirroring). If you've got a bunch of money to throw at it and you want both, do raid 1 + 0; mirrored stripe sets (different raid channels or controllers for each stripe set). In most cases, switching raid levels requires re-installing your server. Marc Creviere
