If you are curious why this is geek news, ZFS (Zettabyte file system) is a file system developed by Sun Microsystems. In theory, ZFS has no theoretical limit for a single file, but the whole filesystem can be as big as one zettabyte (a zettabyte is one million terabytes) unlike some of the current file systems out there like NTFS (the filesystem that Windows XP uses) and HFS+ (the current OS X filesystem) which have file limits of 16TiB. Plus it has other cool features like storage pools and intelligent drive mirroring.
The idea is this could be the direction the computer file system is headed.
So I think it qualifies as Geek News.
