The TERRAMASTER U4-500 is a high-performance 1U rackmount NAS (Network Attached Storage) designed for small to medium-sized businesses that require robust data storage, backup, and management solutions. It is built to handle demanding workloads such as video editing, virtualization, and large-scale data processing. The device is diskless, meaning it does not come with pre-installed hard drives, allowing users to configure it with the storage capacity that best suits their needs.


With a powerful 12th Gen Intel Core i3-1215U processor, the U4-500 delivers business-grade performance. This processor features six cores and eight threads, with a turbo boost frequency of up to 4.4GHz, ensuring smooth multitasking and efficient handling of complex tasks. The inclusion of 8GB DDR5 RAM further enhances performance by providing faster data access and improved multitasking capabilities.


The U4-500 is equipped with dual M.2 NVMe slots that support Hyper Cache technology. This feature significantly boosts storage efficiency by accelerating read and write speeds, making it ideal for applications that require fast data access such as backups and media production. Additionally, the device features Intel UHD Graphics with AES-NI hardware encryption, which provides secure and accelerated data processing.


The dual 10GbE network ports offer a combined bandwidth of 20Gbps and support SMB multichannel for ultra-fast data transfers. This makes the U4-500 suitable for environments where high-speed network connectivity is essential. The NAS also supports a variety of RAID configurations, including RAID 0, 1, 5, 6, 10, TRAID, and TRAID+, allowing users to optimize storage performance and redundancy according to their specific needs.


The device supports up to four hard drives in a 4-bay configuration, with the ability to use hybrid SSD/HDD setups for tiered storage. This allows users to balance performance and capacity effectively. The maximum storage capacity can reach up to 96TB when using four 24TB hard drives.


The U4-500 offers professional file system options such as EXT4 for stability or Btrfs for advanced data protection with features like snapshots and checksums. It also includes a comprehensive backup suite with tools like TERRAMASTER BBS for centralized backup, TerraSync for synchronization between servers and PCs, Duple Backup for off-site recovery, CloudSync for cloud-based recovery, and Snapshot for ransomware protection.
