Hello Justin,

what is your typical bonnie++ invocation, to test your configuration?
Which fields are meaningful for you from this benchmark?

Do you use anything else for benchmarks? 
eg: 'zcav /dev/sda > result' ?


I'm asking becuase I want to make some local benchmarks to determine
best chunk size in my HDD setup.

thanks in advance
