Yes... what does that have to do with what I said? My point was that as long as you are IO bound, it doesn't make much difference between having to read all of the disks in the stripe for a raid6 and having to read some number that is possibly less than that for a raid10. They both take about the same amount of time as just writing the data to the new disk.
