Overview

The QNAP TS-864eU-8G is a short-depth 1U rackmount NAS built around an Intel Celeron N5105 quad-core processor with burst speeds up to 2.9 GHz and 8GB of non-expandable DDR4 memory. Its eight 3.5-inch SATA bays accept both hard drives and SSDs, supporting RAID 0, 1, 5, 6, 10, and JBOD configurations for flexible data protection. Two M.2 PCIe Gen 3 x1 NVMe slots sit inside the chassis, letting administrators add SSD caching to accelerate random read/write performance or create dedicated SSD storage pools for latency-sensitive applications. Dual 2.5GbE RJ-45 ports provide networking with link aggregation support, while multiple USB 3.2 Gen 2 Type-A ports at 10Gbps allow direct-attached backup to external drives or QNAP expansion enclosures.

Beyond raw storage, the TS-864eU includes an HDMI 1.4b output capable of 4K playback at 30Hz with real-time hardware transcoding, making it viable as a media server for digital signage or conference rooms. QNAP's software ecosystem adds practical value: Boxafe handles automated backup of Google Workspace and Microsoft 365 accounts, QVR Pro provides IP camera surveillance management, and built-in snapshot technology offers ransomware protection with point-in-time recovery. At roughly 17.72 inches deep, the chassis fits comfortably in shallow wall-mounted racks and compact server closets where standard-depth equipment cannot be installed, making it a practical choice for offices, retail locations, and remote sites with limited infrastructure space.

Pros & Cons

👍 Pros

  • Eight drive bays in a short-depth rackmount chassis fit shallow racks and cabinets
  • Dual 2.5GbE ports support link aggregation for up to 5Gbps combined throughput
  • M.2 NVMe SSD slots allow SSD caching or dedicated SSD pools without using drive bays
  • Multiple USB 3.2 Gen 2 ports at 10Gbps enable fast external backup and expansion
  • HDMI 1.4b output with 4K playback and hardware transcoding built in

👎 Cons

  • 8GB on-board RAM is non-expandable, which may limit heavy multitasking or virtualization
  • PCIe Gen 3 x1 bandwidth on the M.2 slots caps NVMe SSD performance well below drive capability
  • Intel Celeron N5105 processor lacks the power for demanding simultaneous transcoding and file serving
  • Dual 2.5GbE networking falls short of the 10GbE speeds found on competing rackmount units at this tier
  • Unit weighs over 20 pounds, making solo rack installation more difficult

Frequently Asked Questions

It comes with 8GB of DDR4 RAM soldered on-board. The memory is non-expandable, so 8GB is the maximum this unit supports.
The TS-864eU has a chassis depth of approximately 17.72 inches, making it suitable for shallow network cabinets and wall-mounted racks where standard-depth servers would not fit.
Yes. The dual M.2 PCIe Gen 3 x1 NVMe slots can be configured as SSD cache to accelerate hard drive performance, or they can be set up as their own SSD storage pool for frequently accessed data.
Yes. QNAP includes QVR Pro surveillance software, which allows you to connect IP cameras for 24/7 recording and monitoring directly from the NAS.
It supports RAID 0, 1, 5, 6, 10, and JBOD, giving you flexibility to prioritize speed, redundancy, or a balance of both across the eight drive bays.
