RAID 0,... Cache size very important for RANDOM?

For 2 HDDs in RAID zero will hdds with a cache size of 32MB significantly outperform similar disks but with 16MB for Random work?

Thanks
 
better to has 512 or 1GB controller cache - imo. then the controller can predict read ahead and write laddering for optimization.

the cpu on the raid controller has more power and battery back-up - iirc the cache on most drives is unprotected from power fail?
