If he combined them, it would be likely he would have to move to an HDD to fit everything. The part that's really unfortuante about that is that HDDs do not have the best reading/writing since the heads actually need to seek the data. These creates performance bottlenecks, especially if he's trying to transfer a build while the database is active. Fewer disks, less chance of failure. it's extra important to back up though, since one disk failure can result in entire catastrophe! Losing an OS but still having DB and Code isn't that catastrophic.
