A short-depth, high-performance, rackmount NAS that’s perfect for IT environments where space is at a premium.
QNAP has launched the TS-h765eU, a 1U short-depth rackmount NAS designed for businesses, industrial applications, and multimedia uses where space is at a premium. Featuring a compact chassis that measures only 292.1mm (12 inches) in depth, this 7-bay NAS (4 HDD, 3 SSD) is ideal for small media cabinets, wall-mounted network racks, mobile broadcasting setups, and edge storage environments.
Aimed at organizations planning long-term deployments, the TS-h765eU is guaranteed to be available until 2031. This ensures hardware consistency for businesses that require a stable, uniform storage infrastructure across multiple sites or extended projects.
Performance and Processing Power
The TS-h765eU is powered by Intel’s Atom x7405C quad-core processor, which can operate up to 3.4GHz. This 64-bit x86 processor is designed to handle multi-threaded workloads, making it suitable for data backup, virtualization, surveillance storage, and media streaming applications. The CPU also features AES-NI encryption acceleration, improving the performance of encrypted data transfers.
The system has 8GB of DDR5 RAM (one SODIMM slot, pre-installed with a single 8GB module), offering lower power consumption and higher bandwidth than DDR4. It supports In-Band ECC (IBECC), a memory error detection and correction technology that enhances system stability. Users can upgrade the RAM to a maximum of 16GB for improved performance in demanding workloads.
Flexible Storage and SSD Optimization
The NAS includes four 3.5-inch SATA drive bays, supporting HDDs and 2.5-inch SSDs. Allowing users to balance high-capacity hard drives and high-speed flash storage.
Among its more notable features are three built-in E1.S/M.2 PCIe NVMe slots, providing multiple storage configuration possibilities:
- High-speed SSD storage pools for primary workloads
- SSD caching to accelerate frequently accessed data
- 10GbE networking upgrades using QNAP’s E1.S to 10GbE network modules
The E1.S SSD slots also support different SSD thicknesses (5.9mm, 9.5mm, and 15mm), offering hot-swappable storage with power-loss protection (PLP) and better thermal efficiency than standard M.2 SSDs. The TS-h765eU also includes 8GB of flash memory for dual-boot OS protection, ensuring system reliability during firmware updates.
Networking and Connectivity
The TS-h765eU features two 2.5GbE ports, allowing faster data transfers than traditional 1GbE networks. Businesses handling large file transfers, high-resolution media, and virtualization can benefit from the improved bandwidth and efficiency.
For users needing even higher speeds, the system supports:
- Upgrading to dual 10GbE ports using an E1.S-to-10GbE network adapter
- Port Trunking (link aggregation) for increased throughput and failover protection
- SMB Multichannel support, which enhances network performance for Windows users by utilizing multiple network connections simultaneously
The NAS also features a USB 3.2 Gen 1 port, enabling direct-attached storage expansion through QNAP’s TR-004U USB JBOD unit. This is a valuable option for businesses that need additional backup capacity without investing in significant network expansions.
ZFS-Based Operating System and Data Protection
The TS-h765eU runs QuTS hero, QNAP’s ZFS-based operating system–designed to prioritize high data integrity and enterprise-grade storage management. One of the key benefits of ZFS is its end-to-end checksums, which help detect and correct silent data corruption, ensuring long-term data reliability.
Additionally, advanced snapshot and versioning capabilities allow users to create multiple restore points, making data recovery quick and efficient in case of accidental deletions or system failures. The system also includes WORM (Write Once, Read Many) protection, which prevents unintended modifications or deletions of critical files. This is especially useful for compliance and archival storage. To optimize storage efficiency, ZFS supports data deduplication and compression, reducing the overall storage footprint and improving performance by minimizing redundant data.
Beyond storage, the TS-h765eU offers GPU passthrough support. It allows users to leverage dedicated graphics power for AI-driven video analytics, virtualization, and media rendering, making it a versatile solution for businesses handling intensive computational workloads.
Designed for Long-Term Reliability and Expansion
QNAP has built the TS-h765eU with future-proofing in mind, ensuring businesses can expand their storage and networking capabilities as their needs evolve. Key reliability features include:
- Hot-swappable drive bays and SSD slots, allowing uninterrupted operation during storage upgrades
- Wake-on-LAN (WOL) and Jumbo Frame support, improving power efficiency and network performance
- Three built-in 40mm cooling fans help maintain stable operating temperatures
- Support for up to 1,500 concurrent CIFS connections, making it suitable for multi-user environments
With its low power consumption, compact footprint, and versatile storage options, the TS-h765eU is a strong fit for small IT rooms, remote sites, and mobile deployments where traditional NAS units might be too large or power-hungry.
