Not necessarily. It depends what you are doing. If you're going to be
running only one database connection at a time, doing really big complex
queries, then having really fast CPUs and discs is better than having
lots. However, that situation is rare.

Agreed. Unless you don't care about the data and need the space, where
RAID 0 might be useful, or if you really don't need the space, where RAID
1 might be okay. If your controller supports it.
