I've had my ear bent about some more putative performance advantages to char() fields, in that SQLServer can find the n'th data field more efficiently, so that you should put the char() fields to the front of the record and the varchar()'s to the end.

No idea if it's true or significant. Hope it's not too significant, since I've never actually paid any attention to it!
