What database are you using where you are concerned with block size? Just for the record, Paradox is evil, lol.

Being serious though, for Paradox, all we ever did was determine record size * expected size of dataset, then changed the block size to reflect those size requirements with a margin of error torward to large a block size.

Either way, if you have a problem, you can change the block size of the data set to a larger size with a rebuild of the data structure, so it really wasn't critical.

It is an Oracle database, and from what I understand you can't change the block size after creation.  Thank you, though....

The other thing to note (if you are putting specific tables on specific disks or something fancy like that) is the vital importance of understanding that your volume estimates will be wrong - give yourself contingency space and understand that the relative sizes of tables may change due to changes in the outside world.
