Even if you're doing a lot of random IO? I would think that random IO would perform better if you use smaller (8K) blocks, since there's less data being read in and then just thrown away that way.
The overhead of reading an 8k block instead of a 32k block is too small to measure on modern hardware. The seek is what dominates; leaving the read head on a little longer and then transmitting a little more over a 200 megabyte channel is statistical fuzz. Mike Stone
