A lot since the load on the system is expected to increase by up to 100% over 
the next 6 months.

I thought I mentioned that in the earlier post but it was from a 2 hour 
period. It's a busy system.

> How much Cache do you have on the controller?

64Mbytes but I don't think that's an issue. As I mentioned in the first post 
the table that is the bottleneck has indexes on 15 columns and is seeing a 
lot of inserts, deletes and updates. The indexes are spread out over the 5 
mirrors but it's still a couple of writes per mirror for each operation. I'm 
going to order an SSD which should give us a lot more headroom than trying to 
rearrange the RAID setup.
