TrueNAS® M-Series

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.
