OSAM is better because with even block sizes you can have a
maximum size of 8 GB for a dataset. OSAM supports
sequential buffering, reads 10 consecutive blocks with one
1 I/O operation. This will reduce the elapsed time by 50%.
It also supports queued writes which also results CPU and
elapsed time savings.
