Subject: A single hash table or two hash tables?

In my chess program I'm using a single transposition hash table. When I will
store info it, and already are info on it for the position, I check if the info
in the table has a smaller depth. If this is correct, I replace it with the new
info.
I saw that other people use two transposition hash tables: one "always replace"
and other with a "special replace scheme".
What's the difference between the "special replace scheme" and the system that I
use?
How much in the improvement using two hash tables, one with "always replace"?

Thanks
