hi: I have a 4 disk software raid6. I found chunk size 512k give me best performance for my workload. if I grow up the raid to 32 disks, may I assume chunk size 64K will give me similar performance? or there will other impact when I grow the disks in the future? I saw discussion about internal bitmap hit the performance for 20 disks raid10. is raid5/6 ok under the same situation? thanks a lot for help!
