The World's Most Deployed
Open Storage
Enterprise-grade NAS, SAN, and unified storage powered by OpenZFS. Free, open, and built to protect your data for decades.
Trusted by organisations of every size
Why organisations choose TrueNAS
Storage is the foundation of everything. TrueNAS combines the reliability of OpenZFS with enterprise features — at a fraction of the cost of proprietary alternatives.
Data Integrity You Can Count On
OpenZFS provides end-to-end checksumming, self-healing RAID, and copy-on-write snapshots. Silent data corruption is detected and fixed automatically — before you even know it happened.
Enterprise Features, Open Source Pricing
TrueNAS CORE is completely free. Enterprise editions add HA, support, and management tools at a fraction of what NetApp, Pure Storage, or Dell EMC charge for equivalent functionality.
Scales from Desktop to Petabyte
Run TrueNAS SCALE on commodity hardware at your desk or deploy TrueNAS Enterprise on certified systems in multi-site clusters. The same software, the same management interface, at any scale.
Why TrueNAS is the platform of choice
A unified storage platform built on 20+ years of OpenZFS development — delivering enterprise data protection, flexibility, and performance at every tier.
OpenZFS Data Protection
The gold standard for data integrity. End-to-end checksumming catches silent corruption, RAIDZ protects against drive failures, and automatic scrubbing keeps your data clean — all without performance penalties.
Snapshots & Replication
Instant, space-efficient ZFS snapshots protect against ransomware and accidental deletion. Replicate datasets to remote TrueNAS systems or cloud storage for comprehensive disaster recovery.
Unified NAS + SAN + Object Storage
SMB, NFS, iSCSI, Fibre Channel, S3-compatible object storage — all on a single platform. TrueNAS serves every workload from file sharing to VM block storage to cloud-native applications.
Apps, VMs & Containers
TrueNAS SCALE adds Kubernetes-powered application deployment, Linux VM hosting, and Docker containers — turning your storage appliance into a full hyperconverged infrastructure platform.
OpenZFS — The Foundation
TrueNAS is built on OpenZFS, the most advanced storage file system ever created. Originally developed by Sun Microsystems, OpenZFS has been continuously improved by a global community for over 20 years.
- Copy-on-write — every write is atomic. Power failures never corrupt data.
- End-to-end checksums — every block verified on every read. Bit rot has nowhere to hide.
- Intelligent caching — ARC, L2ARC, and ZIL optimise reads and writes automatically.
- Native compression & deduplication — store more, spend less on raw capacity.
Snapshots & Replication That Just Work
TrueNAS makes backup and disaster recovery effortless. ZFS snapshots are instant and space-efficient — schedule them every 15 minutes without impacting performance.
- Instant snapshots — point-in-time copies in milliseconds, no storage penalty until data changes.
- Ransomware protection — immutable snapshots attackers can't encrypt or delete.
- Automated replication — push datasets to remote TrueNAS, cloud providers, or S3 targets on a schedule.
- Cloud sync — built-in connectors for AWS S3, Backblaze B2, Azure, Google Cloud, and more.
Every Protocol, One Platform
Stop buying separate file servers, iSCSI targets, and object stores. TrueNAS serves every storage protocol from a single management interface.
- SMB & NFS — Windows and Linux file sharing with Active Directory integration.
- iSCSI & Fibre Channel — block storage for VMware, Hyper-V, and bare metal workloads.
- S3-compatible object storage — store application data and backups using the industry-standard S3 API.
- WebDAV & FTP — simple remote access for legacy and web-based applications.
From home labs to hyperscale clusters — a TrueNAS for every use case.

Everything you need to protect and serve your data
Storage and Data Protection
OpenZFS delivers the most comprehensive data protection available in any storage platform — included in every TrueNAS edition.
OpenZFS Pools & Datasets
Organise storage into pools and datasets with per-dataset compression, deduplication, and quota settings.
RAIDZ, Mirror & Stripe
RAIDZ1, RAIDZ2, and RAIDZ3 configurations protect against 1, 2, or 3 simultaneous drive failures.
ZFS Snapshots
Instant, space-efficient point-in-time copies. Schedule automatically, browse previous versions, and restore in seconds.
Replication & Cloud Sync
Replicate datasets to remote TrueNAS systems or sync to S3, Azure, Google Cloud, Backblaze B2, and more.
Scrub & Self-Healing
Scheduled scrubs verify every block. Checksums detect and automatically repair silent corruption from RAIDZ parity.
Encryption
