TrueNAS Core Overview

Experience Storage Freedom

TrueNAS® CORE (formerly known as FreeNAS®) is the world’s most popular storage OS because it gives you the power to build your own professional-grade storage system to use in a variety of data-intensive applications without any software costs. Simply install it onto hardware or a VM and experience the true storage freedom of open source storage.

Share Files. Serve Media. Store Anything.

TrueNAS CORE can be used from the home to the office to the data center for a variety of data-intensive use cases. IT professionals, photographers, designers, audio/video producers and editors, developers, and any user serious about storing and protecting lots of data can take advantage of TrueNAS CORE. Pair it with your favorite backup software to archive large quantities of infrequently used data off of your local devices and even sync and push data to the cloud.

Nothing Protects Your Data Like ZFS

At the heart of TrueNAS is the self-healing OpenZFS filesystem. Previously only available on the highest-end enterprise storage systems, TrueNAS gives you direct, user-friendly access to ZFS. With its built-in RAID, powerful data management tools, and ability to automatically detect and repair silent data corruption (and bit rot), TrueNAS and OpenZFS ensure data integrity from start to finish.

Go Beyond “NAS”

More than a traditional “Network Attached Storage”, TrueNAS is Unified Storage that integrates seamlessly into any environment with a variety of file, block, or object access protocols. You can also expand its functionality with a variety of free plugins, like Plex Media Server, NextCloud, Zoneminder surveillance, and many others.

Manage Your Data Like a Pro

Unlimited snapshots, clones, and replication add additional layers to safeguard your data from human error or external threats like ransomware. Add system memory (DRAM) and flash to supercharge performance. Use built-in data compression to maximize space. Manage it all from a user-friendly web interface.

Join the TrueNAS Community

Need help? TrueNAS CORE has detailed documentation and a global community of over 250,000 to learn from and collaborate with.

If your data is critical or you simply need professional support, TrueNAS Enterprise and the full line of TrueNAS storage appliances provide enhanced features and the around-the-clock support necessary to keep your storage online.
