When you say 57% reduction, do you mean performance goes from (say) 1000 
IOPS to 430 IOPS, or that you get 57% of the peak performance (1000 IOPS 
-> 570 IOPS)?

Because if it's the former 80% reduction (i.e., 20%) sounds bad.  But I'm 
guessing you mean you get 80% of the original performance?

Thanks!
