We are using 3.10 and have a 7 PB cluster. We decided against 16+3 as the rebuild time are bottlenecked by matrix operations which scale as the square of the number of data stripes. There are some savings because of larger data chunks but we ended up using 8+3 and heal times are about half compared to 16+3.
