NAS4Free is an embedded Open Source Storage NAS (Network-Attached Storage) distribution based on FreeBSD. This project is a continuation of FreeNAS 7 series project. NAS4Free is based on FreeBSD 9.x whereas FreeNAS 8 is based on nanoBSD, hence the name change. This makes sure that users are not confused about both projects. NAS4Free supports sharing across Windows, Apple, and UNIX-like systems. It includes ZFS v28, Software RAID (0,1,5), disk encryption, S.M.A.R.T / email reports, includes the following protocols: CIFS (samba), FTP, NFS, TFTP, AFP, RSYNC, Unison, iSCSI (initiator and target), UPnP, and Bittorent which is all highly configurable by its WEB interface.

NAS4Free can be installed onto a wide range of hardware. Anything from a actual server to an old PC you may have laying around. Please check the hardware compatibility wiki as well for more details. NAS4Free has 2 different installation methods plus a livecd mode.

The livecd mode allows you to try out NAS4Free for the first time or run a NAS4Free server using your livecd via cd-rom and a USB/Floppy disk in which the NAS saves your configuration files. What this means is that every time you boot from the livecd, NAS4Free will load the required config.xml file that stores all your server settings. To update to newer revisions of NAS4Free you will have to download a new livecd iso (~154Mb).
The 2 installation methods are "full" install or an "embedded" install. The full install allows you to install NAS4Free to a internal hard drive (HDD) or solid state drive (SSD) with a system, data, and swap partition. With this method, you do use a valuable IDE/SATA port that could be used to have an additional storage drive. To update the system you would have to download the full livecd iso, boot from it and select the upgrade option.The embedded installation method is truly what NAS4Free was designed for. With an embedded install you would install the system onto a USB key or a compact flash card (CF). You do however have the option of installing embedded onto a HDD/SSD, but again you lose a valuable IDE/SATA port that could be used for addition storage drives and defeats a key advantage of having an embedded system. The other key features of an embedded install are less system writes when using embedded which means that the USB/CF last much longer and how you update your NAS4Free system. With an embedded system update you download a special firmware (~76mb) that is in a .img format which is much smaller than the livecd iso. Once you download the firmware, updating is a breeze. All you do is open the webgui in your browser of choice, select firmware from the system navigation menu, enable firmware updates, browse for the image file, click update, and let the system do the rest. The system will load the file, update the system, reboot, and your done. NAS4Free: Features All NAS4Free versions:
