You could evenuse a processor dedicated for such a job, like a PPC440SPe or PPC460SX or similar, which provide hardware-offload capabilities for the RAID calculations. These are even supported by drivers in mainline Linux. But again, thee would not helpo to maximize IOPS - goal for optimization has always been maximum sequential troughput only (and yes, I know exactly what I'm talking about; guess where the aforementioned drivers are coming from).
