There are a couple more considerations.
1. you have no plans for hot spares in your arrays. Recommend (3) U160
drives for OS and (7) drives for data
2. I don't recommend raid5 when 0+1 or 10 are much better performance wise.
Personally I would combine all (7) u160 drives for your data volume and only
get three u320 drives for the OS. Less to purchase. You don't mention a
u320 controller nor do you mention dual channel. If going to u320 it has to
be supported by the raid backplane [u320 into a u160 backplane will only work
at u160 or not at all], the connecting cable and the raid card. In other
words you will have to replace the external u160 raid cage with a u320
version. You would have to have a dual channel raid card if you expect to
cable both the internal and external arrays and combine them into a hardware
raid array.
Make sense?
