NAS4Free - The Free Network Attached Storage Project

 NAS4Free logo NAS4Free is an embedded Open Source Storage NAS (Network-Attached Storage) distribution designed for home users and small businesses primarily, but could potentially scale to larger projects.


Some users assume that NAS4Free is a “fork” of FreeNAS. This is absolutely NOT the case.

NAS4Free is the direct continuation of the original FreeNAS code that was under development from 2005 till 2011 under the name FreeNAS.

After the FreeNAS name was legally acquired by iXsystems, Inc. (year 2011), the code was unable to be developed any longer under the same name, and a name change was necessary. The founder of FreeNAS (Olivier Cochard-Labbé) did donate the original FreeNAS code to our project. IXsystems no longer wanted us to release new builds under the FreeNAS name, so the only option was to leave the FreeNAS project after so many years.

At the time we began publishing the new name. Many necessary updates were done, including upgrading the base system. NAS4Free went up from FreeBSD 7 to the FreeBSD 9.x releases, allowing support for a lot of newer hardware too. This includes great advances in ZFS version support as well. These changes should vastly increase our ability to offer you an even better NAS system than ever before.

NAS4Free is intended to be installed, most often, in its Embedded form. This provides the installed system a high degree of damage resistance (against accidental or intentional tampering) and allows you to update VERY easily. Full installs do NOT have this resistance to damage and are difficult and/or annoying to update.


To facilitate the user interface, a WEB configuration interface (originally based on m0n0wall) is used.

NAS4Free supports sharing with UNIX-like, Apple, and Windows systems (and others that use the same or compatible network protocols).

Some supported protocols include: CIFS/SMB (Samba), FTP, NFS v4, TFTP, AFP, RSYNC, Unison, iSCSI (initiator and target), UPnP, Bittorent and Bridge, CARP and HAST protocols.

It supports ZFS, Software RAID (0,1,5), UFS, Disk Encryption, and S.M.A.R.T with Email notifications.

NAS4Free can be booted of from a LiveCD or LiveUSB, and optionally installed on Compact Flash, USB flash drive, SSD, Hard drive or a number of other bootable devices. (NAS4Free also supports advanced formated drives using 4kb sectors)

NAS4Free-ARM series downloads are also available on SourceForge Project NAS4Free:

  • Always Read the readme.txt before you download and install, it often contains very important information!

Unless you know WHY you're downloading the .img file, then you really don't want the .img file. You want the .iso. (trust me)

The NAS4Free team hopes you enjoy your experience with our software and that it is your perfect NAS solution for your home or business!




In the IRC channel, don't ask if anyone can help you, wait 10 minutes, and then leave. That helps nobody.

Just ask the question(s) you really have.
If someone can help, then sooner or later you'll get a response. (may take over an hour) A lot of people idle in the IRC channel, and just never leave, but that doesn't mean that they'll be available to help immediately. If you don't or can't just ask your questions and wait around for an answer, the IRC channel may not be a good option for you.
