WRT the question of whether smaller block sizes will allow Oracle to perform better, I don't see where it can have any impact (one way or the other). From my perspective it is kind of like asking which pizza will fill you up more; a 12 inch pizza cut into 4 slices or a 12 inch pizza cut into 8 slices. A 12" pizza is the same size; regardless of how you slice it.

The smaller block size does NOT change the number of I/O operations which will hit the disk drive. I fail to see how the smaller block size can change the amount of activity that needs to be done by the disk drive. In fact I could argue that because of the increased overhead from having a smaller block size, the performance would actually decrease.
