The TerraMaster U4-500 is a 4-bay NAS file server designed for small and medium-sized businesses that need secure data storage, centralized file management, and an advanced backup system. The device is equipped with an Intel Pentium Gold 8505 processor with 5 cores and a clock speed of up to 4.4 GHz, 8 GB of DDR5 memory expandable up to 64 GB, two 10GbE ports, two M.2 NVMe slots for SSD caching, and four drive bays with a total capacity of up to 96 TB. Thanks to its compact 1U design, support for multiple RAID levels, and the comprehensive Business Backup Suite, it provides a complete solution for enterprise data protection and management.
At the heart of the server is the Intel Pentium Gold 8505 processor, which delivers high performance when handling multiple users, network services, and backup tasks. The pre-installed 8 GB of DDR5 memory ensures smooth system operation, and the ability to expand up to 64 GB allows you to adapt the device to your company’s growing needs. An additional advantage is the two M.2 NVMe PCIe 4.0 slots, which can function as SSD cache, accelerating access to frequently used data. This combination makes the server well-suited both as a central file repository and as a platform for running business applications or virtual environments.
The U4-500 model is equipped with two 10GbE network ports, which enable very fast data transfer within the corporate network. Link aggregation increases bandwidth and improves service availability, which is particularly important when multiple users are working simultaneously. It also features three USB 3.1 Type-A ports, a USB-C port, and an HDMI output, which expand integration capabilities with other devices. With support for SMB, NFS, FTP, SFTP, and WebDAV protocols, the server works seamlessly with computers running Windows, macOS, and Linux.
The TerraMaster U4-500 was designed as an integrated backup server, which is why it offers access to the Business Backup Suite. This suite includes Centralized Backup, TerraSync, Duple Backup, CloudSync, and Snapshot, which enable the creation of local and remote backups. The administrator can centrally manage backups of employee computers, physical servers, and virtual machines without having to configure each device individually. This makes the data protection process simpler, faster, and easier to control.
Data loss can result in downtime and real financial losses, which is why the U4-500 offers multiple layers of security. The system supports file and volume snapshots, AES data encryption, SSL certificates, OTP authentication, and automatic blocking of suspicious login attempts. A built-in firewall and advanced protection mechanisms help secure company resources against ransomware and unauthorized access. Thanks to remote backup and disaster recovery features, your business can get back up and running faster, even after serious incidents.
