However, the code is not going to be significantly more complex due to this, and I think it's a much better, ie cleaner, way of doing it. > One thing I am finding myself doing a lot these days is increasing the > block size for things like /data1 - that will often have fewer larger > files.

I tend to use a block size of 16K to get the number of cylinder groups down to semi-sane levels.
