TerraMaster has launched the 725 Series, four Intel Xeon D rackmount NAS systems aimed at enterprise file storage, backup, virtualization, media production, and AI dataset storage: the U8-725, U12-725, U12-725 Plus, and U16-725 Plus. Every model ships with 16GB of ECC memory, four 10GbE SFP+ and two 5GbE ports, and three M.2 slots for PCIe 4.0 NVMe SSDs. The standard models use the 4-core Xeon D-2712T, and the Plus models step up to the 8-core Xeon D-2733NT.
Xeon D, 50Gbps of Networking, and PCIe 4.0 Expansion
The U12-725 pairs the Xeon D-2712T (4 cores, 8 threads, 1.9GHz base, 3.0GHz turbo) with 16GB of DDR4 ECC memory, expandable to 1TB across eight DIMM slots. Its four 10GbE SFP+ and two 5GbE RJ45 ports add up to 50Gbps of network bandwidth, and the chassis offers four PCIe expansion slots (two PCIe 4.0 x8, one PCIe 3.0 x8, and one PCIe 4.0 x4) alongside the three M.2 slots. The Plus models use the Xeon D-2733NT (8 cores, 16 threads, 2.1GHz base, 3.2GHz turbo) with the same memory and networking. The 8- and 12-bay models are 2U, and the U16-725 Plus is a 3U chassis with three PCIe slots. All four ship with an 800W power supply, with a redundant option available.
Under TerraMaster’s laboratory test conditions, the company says the U12-725 reached up to 6,250MB/s sequential read, up to 3,480MB/s sequential write, and up to 945,063 IOPS in 4K random reads. TerraMaster notes that actual performance varies by hardware configuration, RAID mode, network environment, and workload, and its U8-725 product page cites the same 6,250MB/s read figure in network aggregation mode on RAID 6. That figure equals the 50Gbps combined line rate of all six network ports.
Four Rackmount Models for Consolidated Storage
The 725 Series targets enterprise file storage and collaboration, backup and disaster recovery, virtualization, 4K and 8K media production, AI training dataset storage, and video surveillance. TerraMaster positions the systems as unified storage platforms for organizations consolidating these workloads onto a single rackmount NAS.
| Model | Drive Bays | Processor | Positioning |
|---|---|---|---|
| U8-725 | 8-bay, 2U | Xeon D-2712T (4-core) | Enterprise file storage, backup, and virtualization |
| U12-725 | 12-bay, 2U | Xeon D-2712T (4-core) | High-performance unified storage, media, AI data, and surveillance |
| U12-725 Plus | 12-bay, 2U | Xeon D-2733NT (8-core) | High-concurrency, AI, virtualization, and professional media |
| U16-725 Plus | 16-bay, 3U | Xeon D-2733NT (8-core) | Large-scale enterprise data and demanding workloads |
Maximum raw capacity runs from 240TB on the U8-725 to 360TB on the two 12-bay models and 480TB on the U16-725 Plus. TerraMaster says the lineup gives distributors, resellers, system integrators, IT service providers, and security integrators configuration options matched to customer data volumes, workload needs, and expansion plans.
TOS 7 Adds Data Search and Indexing Functions
The systems run TOS 7, which TerraMaster describes as its AI-Native operating system, with enhanced capabilities for large-scale data search, indexing, and intelligent management. TOS 7 also runs across the BBS backup servers TerraMaster launched in August.
For AI development teams, TerraMaster positions the 725 Series as centralized storage for training datasets and related data assets. The company also says the platform can provide local data storage for private AI knowledge bases, intelligent applications, and data analytics.
The 725 Series launched on September 22. TerraMaster’s U.S. online store lists the U8-725 at $4,999, the U12-725 at $5,499, the U12-725 Plus at $7,199, and the U16-725 Plus at $8,299, each with 16GB of memory.
