The future of filesystems is not Microsoft’s WinFS (no longer an actual filesystem but instead an API built on top of NTFS) or even IBM’s mainframe lineage XFS. Instead a Linux filesystem known as Reiser4 is poised to change the way we think about computer technology. Check out kerneltrap.org’s interview with Hans Reiser, the creator of Reiser4. Reiser4’s speed looks to be nothing short of revolutionary. Add to it a plugin-able architecture that allows unheard of functionality to take place in filesystem space and you get what could be the most disruptive filesystem technology to be seen sense the advent of the modern computer.
