> The direct Input/Output (I/O) capability makes InterBase more scalable with very large databases on systems where there are memory resource limitations. With the Update 2 release, InterBase enables this "direct I/O" functionality on Windows OS.

It is implemented few years ago in FB 2.1, read Release Notes :
