QNAP TVS-675-8G 8-Bay Tower NAS

Powered by the x86 architecture Zhaoxin KaiXian KX-U6580 8-core processor, the QNAP TVS-675-8G provides businesses with a modern 2.5GbE NAS solution to tackle everyday tasks like file backup/restore, and to boost team collaboration with higher productivity. Besides hardware advantages with built-in M.2 SSD slots for cache acceleration and PCIe expansion, the TVS-675 supports abundant business and media applications (including snapshot protection, virtual machines, cloud storage gateways, 4K HDMI display, and real-time transcoding) alongside expandable storage capacity and install-on-demand apps, making it a cost-effective and reliable data storage and media NAS.

  • Up to 5 Gbps transfer speeds can be achieved by setting port trunking with the two built-in 2.5GbE ports.

  • Install high-performance M.2 PCIe NVMe Gen 3 x1 SSDs or economical SATA 6Gb/s SSDs in the dedicated SSD slots for caching with improved random I/O or high-performance storage pools.

  • Two PCIe Gen 3 slots allow for installing 2.5/5/10GbE adapters, QM2 cards, or QXP storage expansion cards.

  • 4K media playback and real-time transcoding; directly output videos to an HDMI 2.0 display (up to 4K @60Hz).

  • Supports storage for virtualization; hosts multiple virtual machines and containers to run a wide range of applications on one NAS device.

  • Flexibly scale the total storage capacity to match business growth by connecting QNAP expansion enclosures.


High-performance multi-tasking with an 8 core 2.5GHz processor and up to 64 GB RAM

Powered by an x86 architecture Zhaoxin KaiXian KX-U6580 8 cores/8 threads 2.5GHz processor and 8 GB DDR4 memory (expandable up to 64 GB – 2x 32GB, dual channel support), the TVS-675 has enormous processing power to drive virtual machine performance and tackle complex multitasking workloads. AES-NI encryption support boosts encryption performance while also maintaining the security of your NAS data.

Streamline large file transfers and video editing with 2.5GbE

The QNAP TVS-675-8G comes with two 2.5GbE RJ45 (2.5G/1G/100M) LAN ports that allow you to use existing CAT5e cables to upgrade network speeds from 1 Gigabit to 2.5 Gigabit. The dual 2.5GbE ports also support Port Trunking for up to 5 Gbps transmission speeds, improving the business efficiency of bandwidth-hungry applications such as large file transfers, fast backup/restoration, and multimedia transfer & editing.

Future-proof your IT infrastructure for high-speed networks

The TVS-675 is also ideally matched with QNAP’s managed and unmanaged 2.5GbE/10GbE switches to form high-speed, secure, and scalable network environments without going over budget. QNAP also provide 2.5GbE/5GbE/10GbE PCIe cards and USB 5GbE adapters for Windows®/Linux® workstations, allowing you to easily build a high-speed network environment for productive team collaboration.

Faster USB transfers

Featuring two USB 3.2 Gen 2 (10Gbps) and two USB 3.2 Gen 1 (5Gbps) ports, the TVS-675 allows compatibility with faster USB external drives/enclosures for transferring large media files. The TVS-675 also supports USB devices such as mobile phones, uninterruptible power supplies, and printers for greater all-round functionality.

Get performance benefits from SSD caching and Qtier Technology

To attain optimal I/O and reduce latency, you can configure SSD caching by using either 2.5-inch SSDs or the two built-in M.2 2280 SSDs slots (supports high-performance PCIe NVMe Gen 3 x1 SSDs or economical SATA 6Gb/s SSDs, sold separately) in the QNAP TVS-675-8G. Extra M.2 SSD slots can also be added by installing QM2 PCIe cards, allowing you to configure your M.2 SSDs in a RAID 5/6 array to achieve higher sequential speed or a read-only cache speed similar to the performance of a RAID 10 array while maintaining high storage efficiency.
