Must is a bit strong, you can put it anywhere where you like, even where the sun don't shine ;-)

You could tell a bit more details, so the following is just a wild guess:

5 Harddisks minus disk c: minus disk d: minus disk e: leaves us with 2 drives, not exactly what you can use for a raid 5. Or does the fact that d: and e: are on the same line mean that these are partitions on the same physical drive?

In that case, you had probably something in mind with those partitions, e.g. to put software in there. If this was the case, then put your software where you intended it to be.

On the other hand, you just have to ask yourself: What do I want to achieve? Something sooner or later will end up on the raid 5. Since there is quite some write penalty , it better be something that is mostly read. Since datafiles and redologs can get excessive writes, it'll be more sensible to put them *NOT* on raid 5.

If I was you, I'd ask myself why I have a raid 5 in the first place, and start working up from there. If it's for some purpose, use it accordingly. If it's not, get rid of it.
