On: Why are my ZFS disks so noisy?

[jftuga]

Is there an online calculator to help you find the optimal combination of # of drives, raid level, and block size?

For example, I'm interested in setting up a new RAID-Z2 pool of disks and would like to minimize noise and number of writes. Should I use 4 drives or 6? Also, what would be the optimal block size(es) in this scenario?
