ZFS

ZFS stands for Zettabyte File System. A Zettabyte is 2⁷⁰ or 1 billion terabytes.

ZFS is a 128-bit file system, so it can address 18 billion billion (1.84 × 1019) times more data than current 64-bit systems. The limitations of ZFS are designed to be so large that they would never be encountered, given the known limits of physics. [wikipedia.org]

You can make use of the power of the ZFS with the upcoming Tomahawk Desktop.

ZFS was originally designed and implemented by the Sun Microsystems and subsequently incorporated in to the FreeBSD. Upcoming version of the Tomahawk Desktop 2.0 is based on FreeBSD.
