Capacity Powerhouse
The TrueNAS M-Series delivers enterprise storage solutions offering unparalleled performance and reliability for mission-critical operations. Designed with high-availability in mind, it seamlessly integrates open-source economics with enterprise-grade hardware, providing organizations with the flexibility and scalability they demand.
Available in four versatile models—M30, M40, M50, and M60—the M-Series delivers unified file, block, and S3-compliant object storage. These systems support configurations ranging from hybrid to all-flash setups, featuring impressive specifications such as up to 1.5 TB of system memory, TrueCache NVDIMM and NVMe caching, and scalability reaching up to 30 PB of capacity. With networking capabilities that include multiple high-speed connections (up to 4× 100 GbE), the M-Series is adept at handling intensive IT workloads, from virtualization and media production to high-speed file sharing and backup operations.
Built to conserve power, space, and cooling, the M-Series employs a modular hardware architecture that supports diverse applications through its hybrid flash and disk storage pools. High Availability (HA) configurations ensure continuous storage services, while Intelligent Storage Optimization achieves data reduction ratios exceeding 2.5×, maximizing storage efficiency.
