If your disk arms (both of them are predominantly hitting the page file) you have created latency for other non-paging disk activities. System may page faster but apps and other binaries are waiting for disk time due to waiting on near constant paging activity. It' probably hair splitting at this point dedicated spindle for paging vs. just RAID0 but this config works well for me. > > It's not the form factor that causing the drives to fail, but the excessive > heat generated by blades/chassis.

I am actually talking (4) 32 bit TS/XE servers on 1 physical blade (using a bare metal hypervisor like Hyper-V) as it will be able to actually use all of that horsepower. x64 breaks some of our apps, so for now it's out of the picture.
