FreeNAS vs UnRAID

FreeNAS and UnRAID are network-attached storage operating systems based on Open Source operating systems. Both support the SMB, AFP, and NFS sharing protocols, Open Source filesystems, disk encryption, and virtualization.

FreeNAS

This Open Source project was started in October 2005 by Olivier Cochard-Labbé and quickly grew as a popular network-attached storage operating system. By September 2009, the development team realized that FreeNAS would need to be completely rewritten in order to incorporate modern features like a plugin architecture, updates to the base system, and a modern User Interface. To carry this out, the original FreeNAS Team transferred the project to iXsystems, who moved from a m0n0wall and PHP-based architecture to one based on FreeBSD’s NanoBSD embedded build system, the Python programming language, the Django CMS, and the Dojo JavaScript toolkit.

UnRAID

unRAID Server OS 6 is a consumer-oriented, server operating system designed to scale with a system’s hardware and developed by Lime Technology. Its RAID design supports a mix of devices, filesystems, and sharing policies.
