"Free" as in "free and open source" and "NAS" as in
"network-attached storage". The FreeNAS project was founded in 2005 on the principle
that network storage should be available to the world at no cost and
unencumbered by license restrictions.
FreeNAS is an operating system that can be installed on virtually any hardware platform to share computer data storage over a computer network. FreeNAS is the simplest way to create a centralized and easily-accessible home for your data.
