TERRAMASTER T12-500 Pro NAS File Server with Intel Core i7-1255U, 16GB RAM, 12 baysThe TerraMaster T12-500 Pro is an advanced NAS file server designed for small and medium-sized businesses that need a high-performance, secure, and scalable data storage system. It is equipped with a 10-core Intel Core i7-1255U processor clocked at up to 4.7 GHz, 16 GB of DDR5 memory expandable to 64 GB, and 12 SATA drive bays, it offers up to 288 TB of storage capacity. Two 10GbE ports, support for M.2 NVMe PCIe 4.0 drives, hardware encryption, and extensive backup features make this device ideal for use as both a central file repository and a corporate backup server.Performance Designed for Working with Large DatasetsAt the heart of the device is an Intel Core i7-1255U processor with 10 cores and 12 threads, which reaches a frequency of up to 4.7 GHz in Turbo mode. This configuration ensures smooth support for multiple users simultaneously, as well as efficient execution of tasks related to backup, synchronization, and file sharing. The server is equipped with 16 GB of 4800 MHz DDR5 memory, which can be expanded up to 64 GB. This allows the device to be easily adapted to the company’s growing needs without having to replace the entire infrastructure.Up to 288 TB of storage for business growthThe chassis offers as many as 12 bays compatible with 3.5" HDDs, 2.5" HDDs, and SSDs. The maximum raw capacity is up to 288 TB (when using 12 drives with a capacity of 24 TB each). Hot-swap support allows drives to be replaced without powering down the device, which minimizes downtime and simplifies storage management. Additionally, two M.2 NVMe PCIe 4.0 slots allow you to use high-speed SSDs as cache, increasing data read and write performance.High-Speed Network Connectivity for Demanding EnvironmentsThe TerraMaster T12-500 Pro is equipped with two 10GbE ports that can operate in link aggregation mode. This solution enables very high transfer speeds and efficiently supports multiple users simultaneously. In practice, this translates to faster file access, shorter backup times, and more efficient collaboration among teams working on shared resources. These connectivity options are complemented by an HDMI port and high-speed USB 3.1 Type-A and USB-C ports with transfer rates of up to 10 Gb/s.Comprehensive Data Protection and Advanced BackupsThe device serves as an integrated backup server, offering the comprehensive Business Backup Suite. It includes tools for centrally backing up employee computers, synchronizing data, creating snapshots, and recovering data after a failure. Thanks to the Snapshot feature, it is possible to quickly restore previous versions of files, providing effective protection against accidental data deletion or ransomware attacks. The solution imposes no limits on the number of backup jobs or data storage capacity, allowing you to develop flexible data protection strategies.Enterprise-Class SecurityThe TerraMaster T12-500 Pro employs multiple mechanisms to secure data and access to resources. It supports AES encryption for volumes and shared folders, OTP authentication, SSL certificates, and protection against unauthorized login attempts. Additionally, the TOS system offers a firewall, integration with Active Directory and LDAP services, and the HyperLock feature, which enhances the protection of stored data. As a result, the server can be used in both small offices and more demanding business environments.Quiet operation and 24/7 readinessDespite its large capacity and high performance, the device operates quietly enough for an office environment. Three intelligently controlled fans ensure effective cooling of the components, automatically adjusting their speed to the current load. The noise level is just 24.5 dB(A), allowing you to use the server without unduly affecting your work comfort. Low power consumption in disk hibernation mode further helps reduce operating costs during everyday use.IncludedTerraMaster T12-500 Pro NAS serverPower cordRJ-45 network cableQuick start guideWarranty informationSet of mounting screws ManufacturerTerraMasterModelT12-500 ProProcessorIntel Core i7-1255UProcessor architecturex86 64-bitNumber of cores/threads10 cores / 12 threadsMaximum clock speedup to 4.7 GHzRAM16 GB DDR5 non-ECC SODIMMMaximum supported RAM64 GB DDR5Number of memory slots2 × DDR5 SODIMMNumber of drive bays12Supported drives3.5" SATA HDD, 2.5" SATA HDD, 2.5" SATA SSDMaximum capacityup to 288 TB (12 × 24 TB)Hot SwapYesM.2 slots2 × M.2 2280 NVMe PCIe 4.0 x4Supported internal file systemsBtrfs, EXT4Supported external file systemsEXT3, EXT4, NTFS, FAT32, HFS+, BtrfsNetwork ports2 × RJ-45 10GbEUSB ports3 × USB 3.1 Type-A (10 Gb/s), 1 × USB 3.1 Type-C (10 Gb/s)Video outputHDMISupported RAID configurationsTRAID, TRAID+, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, RAID 10Hardware transcodingH.264, H.265, MPEG-4, VC-1Maximum number of concurrent SMB/AFP/FTP/SFTP connections512Noise level24.5 dB(A)Power supply500 WDimensions334 × 165 × 295 mmNet weight7.9 kgOperating temperature0°C – 40°C

SFP1-BIDI-SU 1.25 Gb/s Simplex SC/UPC Module - 20 km AThe SFP1-BIDI-SU module enables a bidirectional fiber-optic connection using only a single single-mode fiber. BIDI technology uses 1310 nm and 1550 nm wavelengths to separate data transmission and reception, reducing the number of fibers required to establish a connection.This solution is suitable both for building new fiber links and expanding existing infrastructure. It allows available optical fibers to be used more efficiently without the need for separate fibers for transmission in each direction.Gigabit Ethernet connection up to 1.25 Gb/s A transmission rate of up to 1.25 Gb/s enables stable Gigabit Ethernet connections between switches, routers, media converters, and other devices equipped with compatible SFP ports.The module can be used, among other applications, to connect distribution points, devices located in different parts of a building, and infrastructure components situated farther apart. Transmission over single-mode fiber helps maintain signal stability even over longer distances.Simplex SC connector for commonly used installations The Simplex SC connector makes it easy to connect the module to fiber-optic links terminated with a standard SC connector. This type of connection is commonly used in fiber distribution frames, telecommunications cabinets, and distribution points.Transmission range matched to the fiber link The SFP1-BIDI-SU is available in versions supporting transmission distances of up to 3 km or up to 20 km. This makes it easier to select the appropriate module for both shorter inter-building connections and more extensive fiber-optic links.The transmission range can be selected according to the link length, the parameters of the fiber used, and the overall optical power budget. This makes it possible to create a solution tailored to the actual network requirements without using a module with an unnecessarily long transmission range.Easy expansion of fiber-optic infrastructure The compact SFP form factor allows the module to be installed directly in a compatible network device. Hot-swappable operation makes it easier to expand or modify the connection configuration without rebuilding the entire infrastructure.The SFP1-BIDI-SU is a practical choice wherever Gigabit Ethernet transmission, efficient use of available fibers, and compatibility with commonly used SC connectors are important.BIDI modules are sold in A and B versions and operate only as a complementary A + B pair. The TX and RX directions are reversed between the two versions: BIDI A: TX - 1310 nm wavelength; RX - 1550 nm wavelength. BIDI B: TX - 1550 nm wavelength; RX - 1310 nm wavelength. A connection using two modules of the same version will not work.
