Overview

The QNAP TS-664-4G is a 6-bay tower NAS built around an Intel processor and 4GB of DDR4 memory, targeting users who need centralized storage with serious data protection. With support for RAID 0, 1, 5, 6, 10, 50, and JBOD, you can configure your drives to prioritize speed, redundancy, or a mix of both. The 2.5 Gigabit Ethernet port provides a meaningful speed boost over traditional Gigabit connections, making large file transfers and multi-user access noticeably smoother — provided your network infrastructure supports the higher throughput.

Running QTS 5.0.1, the TS-664 offers far more than basic file storage. The operating system supports containerized apps, multimedia streaming, automated backups, snapshot protection, and even lightweight virtualization. The tower form factor keeps setup simple — slot in your drives, connect to your network, and configure through the browser-based interface. For users who anticipate storage growth, QNAP expansion units let you add drives beyond the built-in six bays without migrating to a larger chassis. It is a flexible foundation that can scale alongside your data needs.
