Powerfully-Scalable Enterprise Storage: Open Source Economics.

The flagship TrueNAS M-Series line of unified storage arrays are designed with enterprise features, high availability, and maximum performance in mind. Available in two models, the TrueNAS M40 and M50 provide unified file, block, and object storage and are available in single or dual-controller, hybrid, or all-flash configurations. Featuring multiple high-speed networking (up to 100Gb/s), system memory up to 1.5TB, NVDIMM and NVMe caching, and up to 10PB capacity, the TrueNAS M-Series is ideally suited for heavy IT storage workloads, including virtualization, media production, high-speed file sharing, and backup

The TrueNAS M-Series arrays combine the flexibility of unified storage, the performance of solid state flash drives, the capacity of hard disks, the simplified management of a powerful web-based user interface, and white-glove enterprise support. TrueNAS inherits the rich functionality and Open Source economics of FreeNAS® and adds Enterprise-class capabilities.

Every TrueNAS enterprise storage array supports unified block, file, and S3-compliant object storage protocols. Its modular hardware architecture conserves power, space, and cooling while supporting multiple applications with its hybrid flash and disk storage pools. Optional High Availability ensures storage services are not disrupted, while Intelligent Storage Optimization maximizes storage efficiency with typical data reduction ratios of greater than 2.5x.

The TrueNAS M-Series delivers high-performance, scalability, data integrity, reliability, and ease-of-management for companies that never sleep.


Hybrid or All Flash Array? With TrueNAS, you can have both. The TrueNAS M-Series leverages industry-leading cache technology along with ZFS by merging DRAM, nonvolatile memory, and flash (NVDIMM and NVMe/SSD) with high-density spinning disks to deliver low latency flash performance at disk capacity and cost. With up to four 100Gb/s network ports per controller, the TrueNAS M-Series is designed to move terabytes of data at maximum speed.


Data integrity is the name of the game, and TrueNAS leaves nothing about your data to chance. In-flight data corruption is automatically detected and repaired before it ever reaches disk, and bit rot and data decay are identified and scrubbed clean. This ensures data is always pristine. Simply put, what you store on a TrueNAS storage solution today will remain intact for as long as it’s in service.


TrueNAS maximizes storage efficiency by offering compression, deduplication, and thin provisioning at no extra cost. The TrueNAS Adaptive Compression (TAC) algorithm efficiently boosts storage performance while maximizing storage capacity. TAC intelligently adjusts its compression ratio without wasting system resources. Before data is stored, TrueNAS dynamically detects and compresses what it can and skips over any data too inefficient to be worthwhile.


Most storage appliances require additional licenses for advanced features – but not TrueNAS. Unlimited file version retention, restoration, and replication are at your fingertips. Data is automatically protected locally against unintentional alteration, such as ransomware or malware, with minimal storage consumption. Data can be replicated locally, remotely, or to the cloud for backups or disaster recovery. TrueNAS snapshots can also be coordinated with VMware snapshots.

With the power of TrueNAS, any data protection or disaster recovery policy is simple to implement and maintain.
