FreeNAS vs XigmaNAS (Formerly NAS4Free)

FreeNAS and XigmaNAS (NAS4Free) are Open Source network-attached storage operating systems based on FreeBSD. Both support the SMB, AFP, and NFS sharing protocols, the OpenZFS file system, disk encryption, and virtualization.


FreeNAS is an operating system that can be installed on virtually any hardware platform to share data over a network. FreeNAS is the simplest way to create a centralized and easily accessible place for your data. Use FreeNAS with ZFS to protect, store, and back up all of your data. FreeNAS is used everywhere, for the home, small business, and the enterprise.

XigmaNAS (Formerly NAS4Free)

This Open Source project is based on the original FreeNAS 0.7 code and is led by developers Daisuke Aoyama and Michael Zoon. XigmaNAS (Formerly NAS4Free) preserves the m0n0wall/PHP architecture used by the original FreeNAS.
