Overview

The QNAP TS-864eU-RP-8G is a short-depth rackmount NAS built for small and medium businesses that need reliable, always-on networked storage without the footprint of a full-depth server. Its eight drive bays accommodate 3.5-inch or 2.5-inch SATA drives, providing substantial raw capacity for centralized file storage, automated backups, and surveillance recording via QVR Pro. The Intel Celeron N5105/N5095 quad-core processor, bursting up to 2.9 GHz, paired with 8GB of DDR4 memory, handles everyday NAS operations including real-time 4K transcoding through the HDMI 1.4b output.

Dual 2.5 Gigabit Ethernet ports support link aggregation, failover, or network segmentation, giving teams flexible options for balancing throughput and redundancy. Two M.2 PCIe Gen 3 x1 NVMe slots sit alongside the main drive bays, enabling SSD caching or dedicated SSD pools without sacrificing any of the eight primary bays. Multiple USB 3.2 Gen 2 Type-A ports provide up to 10 Gbps connectivity for external storage expansion or fast one-time data imports. The redundant power supply design ensures that a single PSU failure does not take the NAS offline, and QNAP's snapshot-based ransomware protection adds a critical layer of data safety. Cloud backup integration with Boxafe covers Google Workspace and Microsoft 365 accounts, making this unit a comprehensive on-premises data hub.

Pros & Cons

👍 Pros

  • Dual 2.5GbE ports enable link aggregation or network segmentation for faster throughput
  • Redundant power supplies minimize downtime in business-critical environments
  • Short-depth rackmount chassis fits shallow server racks and network closets
  • Dual M.2 NVMe slots allow SSD caching without occupying any of the eight drive bays
  • Built-in HDMI output and 4K transcoding add standalone media playback capability

👎 Cons

  • 8GB RAM is soldered and non-expandable, limiting virtualization and heavy multitasking headroom
  • M.2 slots are PCIe Gen 3 x1, which caps NVMe SSD throughput well below drive capability
  • No 10GbE networking built in, requiring an add-on card for higher-speed infrastructure
  • Intel Celeron N5105/N5095 is an entry-level processor that may bottleneck under heavy concurrent workloads

Frequently Asked Questions

No, the 8GB DDR4 memory is on-board and non-expandable, so what ships in the unit is the maximum available.
The two M.2 PCIe Gen 3 x1 NVMe slots can be used for SSD caching to speed up frequently accessed data, or configured as an SSD storage pool for high-performance workloads.
Yes, it includes an HDMI 1.4b output capable of 4K at 30Hz, allowing direct playback of media stored on the NAS without needing a separate media player.
The RP designation indicates redundant power supplies, and QNAP's snapshot solution provides ransomware protection and disaster recovery capabilities.
It supports up to 8 drive bays and features dual 2.5GbE Ethernet ports that support 2.5G, 1G, and 100M speeds.
