If you have the luxury of being able to test more than one
configuration with something resembling your actual workload, I would
strongly recommend including this as one of your configurations.
Spreading everything over the larger number of spindles might well
out-perform your most carefully hand-crafted tuning of object
placement on smaller spindle sets.
