TrueNAS H-Series
Versatile hybrid or all-flash storage
The TrueNAS H-Series delivers the reliability, unbeatable value and efficient performance of TrueNAS Enterprise at an entry-level price. Available in hybrid or all-flash configurations, the H-Series offers high-availability options for up to 2.5PB in HDD or 1.5PB in flash.

Powerful and efficient performance
The TrueNAS H-Series is a compact 2U system with 12 drives and optional expansion to 114 drives with 2.5PB capacity. Each system can be configured for scalable hybrid capacity or cost-effective all-flash performance. The H-Series is designed for industry-leading total cost of ownership (TCO) with typical power consumption of <300W. Pricing includes TrueNAS Enterprise software. The optional TrueCommand service (licensed separately) can be used to manage single or multiple TrueNAS systems.
Large capacity, Tiny Footprint
Engineered to minimize rack space and power consumption, the TrueNAS H-Series’ slim 2U design delivers efficient performance and capacity for small to medium workloads. Despite its small size, a single TrueNAS H-Series can support up to 2.5PB of raw capacity in just 6U.
Storage you can rely on
Combining the best open source storage technology with enterprise-grade hardware delivers world-class reliability. The OpenZFS file system is the ultimate in data security: copy-on-write and bit-rot detection ensure the integrity of your data from write to read. Dual controllers and high availability options ensure over 99.999% uptime, so you can keep working even during maintenance.
