One spindle in the system volume set is generally accepted as a "bad
thing".
You will have spool files, transient files (read: paging), transaction
manager, and code paging from XL, NL, and other code objects.  Even on
dual spindle configurations, ldev 1 can be a bottleneck.

Bear in mind though when you go to multiple volumes, that MPE will do
it's level best to only allow ldev 1 to reach 50% full, so if you're
choosing spindles, the bigger the capacity, the more you'll waste
(essentially) on
ldev 1 and aggravate fragmentation on other drives.  I'm getting
suitable performance from 2x4Gb internals but I also have Disk Space
Manager from Bradmark (Defrag/X from lund will do this too).

If you can afford it, you might consider 3-4 2Gb drives, I had the 3x2Gb
configuration in another system.
