NAS4Free is a Network-Attached Storage (NAS) distribution designed to be installed on any storage device – hard disk drives (HDDs), solid state drives (SSDs), USB sticks, or be used as a Live system, running directly from a CD or USB stick.

Based on FreeBSD, the codebase is a continuation of the old FreeNAS code, after the latter’s code was redesigned in 2011 soon after it (FreeNAS) gained official support from iXsystems, Inc.

As with FreeNAS, the distinguishing feature of NAS4Free is support for ZFS, the file system most commonly regarded as the best file system on an operating system. ZFS (Zettabyte File System) is the file system designed for Sun Microsystems’ Solaris operating system. Aside from FreeBSD and the distributions that are based or derived from it (FreeNAS, NAS4Free, and PC-BSD), ZFS is also the file system used on illumos distributions.

The latest version of NAS4Free is, which is based on FreeBSD 9.1.
