I'm looking for any type of data that supports whether BCS drives perform better/worse than ZCS drives. In particular, I'd like to see benchmark read/write performance on F760 filers (using ONTAP 6.3.1R1) with FC9 volumes of purely 36GB ZCS or 36GB BCS drives and also volumes of purely 72GB ZCS or 72GB BCS. I looked through the NOW pages but couldn't find anything along these lines. It seems netapp has moved in the direction that all their newer/larger disks tend to be BCS(520) only or am I mistaken? If thats the case then where is the data to show why BCS is better than ZCS. Aside from the fact that you loose a slight amount of disk space on BCS drives what are the pluses? Is there less CPU overhead one way or another?
Thanks,
Steve
