TerraMaster is expanding its enterprise storage efforts around a group of rackmount and tower NAS systems designed for centralized backup, data protection, video surveillance storage, and other business workloads, a step up in ambition from the consumer NAS and Thunderbolt storage the brand is better known for. The current lineup includes the U4-500, U8-500 Plus, U12-500 Plus, T9-500 Pro, and T12-500 Pro, with configurations ranging from four to 12 drive bays.
The systems cover several deployment sizes while sharing many hardware and software features. The U4-500 is the entry model with four SATA bays, while the U8-500 Plus and U12-500 Plus increase rackmount capacity to eight and 12 bays. TerraMaster’s T9-500 Pro and T12-500 Pro use tower enclosures with nine and 12 bays, respectively.
TerraMaster is focusing on two enterprise uses for these systems: data protection and video surveillance storage. Its Business Backup Suite (BBS) handles centralized backups from PCs, servers, and virtual systems, along with synchronization, snapshots, cloud synchronization, and off-site disaster recovery. For surveillance deployments, NAS systems can provide centralized storage and long-term retention for video from IP cameras and existing surveillance systems.
TerraMaster Enterprise NAS Lineup
Most of the higher-capacity systems share an Intel Core i7-1255U processor with 10 cores and 12 threads, 16GB of DDR5 memory, dual 10GbE networking, and two M.2 NVMe slots. The U4-500 uses a Core i3-1215U with six cores and eight threads, along with 8GB of DDR5 memory, while retaining dual 10GbE and two M.2 NVMe slots.
| Model | CPU | Memory | Drive Bays | Networking | M.2 NVMe |
|---|---|---|---|---|---|
| U4-500 | Intel Core i3-1215U, 6 cores/8 threads, up to 4.4GHz | 8GB DDR5 | 4 | Dual 10GbE | 2 slots |
| U8-500 Plus | Intel Core i7-1255U, 10 cores/12 threads, up to 4.7GHz | 16GB DDR5 | 8 | Dual 10GbE | 2 PCIe 4.0 x4 slots |
| U12-500 Plus | Intel Core i7-1255U, 10 cores/12 threads, up to 4.7GHz | 16GB DDR5 | 12 | Dual 10GbE | 2 slots |
| T9-500 Pro | Intel Core i7-1255U, 10 cores/12 threads, up to 4.7GHz | 16GB DDR5 | 9 | Dual 10GbE | 2 slots |
| T12-500 Pro | Intel Core i7-1255U, 10 cores/12 threads, up to 4.7GHz | 16GB DDR5 | 12 | Dual 10GbE | 2 slots |
The U4-500 supports up to four 24TB drives for 96TB of raw internal capacity, while TerraMaster lists up to 192TB for the eight-bay U8-500 Plus and up to 288TB for its current 12-bay configurations when using 24TB drives. The T9-500 Pro supports nine SATA drives, giving businesses another capacity option between the eight- and 12-bay systems.
All five systems support SATA HDDs and SSDs, with RAID options including Single, RAID 0, 1, 5, 6, and 10, as well as TerraMaster’s TRAID and TRAID+. The latter supports online capacity expansion and migration as storage requirements change. Btrfs and ext4 are also available for internal storage. Each system includes dual 10GbE interfaces, with TerraMaster reporting sequential write performance up to 2,090 MB/s via SMB Multichannel.
Centralized Backup and Data Protection
TerraMaster’s BBS software combines several backup and synchronization tools for business environments. Centralized Backup can copy data from employee computers, file servers, and virtual systems to the NAS, while TerraSync handles synchronization and backup between computers and TerraMaster systems.
Duple Backup adds another recovery option by copying folders, volumes, or iSCSI LUNs to another storage system, file server, or cloud destination. It supports incremental and multi-version backups, allowing a secondary copy to be maintained outside the primary NAS. CloudSync extends this to services such as Google Drive, OneDrive, Amazon S3, Dropbox, and Baidu Cloud, supporting local-to-cloud and cloud-to-local synchronization.
Snapshots provide point-in-time recovery for file systems and folders after accidental changes, deletions, or ransomware attacks. Combined with Duple Backup and CloudSync, administrators can also maintain copies of their data on other systems, at another site, or in the cloud.
TerraMaster is also positioning the same NAS hardware for surveillance storage. Connected to IP cameras, network infrastructure, and existing surveillance platforms, the systems can centralize recorded video and support longer retention periods and archival storage.
TOS 7 Adds New Management and Data Features
TOS 7 is the operating system used across TerraMaster’s current NAS platform and includes more than 50 new features compared with the previous release. It handles system management, storage, security, and backup functionality, including access to BBS and TerraMaster’s other applications.
TerraMaster is also preparing TOS 7 for local data use with private AI applications and enterprise knowledge bases. The NAS remains responsible for storing and managing the organization’s local datasets, allowing businesses to maintain their data on local infrastructure as they add applications that use those datasets.
Across the five systems, TerraMaster covers a fairly wide range of business storage requirements without changing the underlying software platform. The choice largely comes down to capacity and deployment type, with rackmount and tower options available for backup, general file storage, surveillance, and other business workloads.
TerraMaster Enterprise NAS Pricing and Availability
TerraMaster currently lists the U4-500 at $899.99, the U8-500 Plus and T9-500 Pro at $1,799.99, and the U12-500 Plus and T12-500 Pro at $2,099.99.
