TrueNAS, the world's most deployed storage software, is a universal data platform that allows users to easily adopt a modern, open source approach to store and protect their growing data. TrueNAS harnesses the power of the legendary ZFS file system to provide unified storage (File, Block Object, and Apps) with the reliability and performance demanded by virtualization, backup, and many other data-heavy workloads. The TrueNAS CORE edition (formerly FreeNAS) is based on FreeBSD for unified scale-up storage. The TrueNAS SCALE edition is based on Debian Linux for either scale-up or scale-out solutions, and offers Linux Containers, VMs (KVM), and scale-out ZFS storage capabilities. Both versions are free to use and work well on a variety of hardware. Join the millions already using TrueNAS, including the majority of Fortune 500 companies, and experience why TrueNAS is so highly rated for yourself.
