Overview

The QNAP TS-664-8G-US is a six-bay desktop NAS built around an Intel Celeron N5105/N5095 quad-core processor that bursts up to 2.9GHz, paired with 8GB of DDR4 memory. It is designed to serve as a centralized storage hub for homes, creative professionals, and small businesses that need to store, back up, and share large volumes of data. The six SATA drive bays accept both 3.5-inch and 2.5-inch drives, and two internal M.2 PCIe Gen3x2 NVMe SSD slots let you add caching or a dedicated SSD pool without using any of those main bays.

Connectivity is a standout feature. Dual 2.5GbE Ethernet ports deliver up to 5Gbps aggregate bandwidth via link aggregation, making large file transfers across a local network significantly faster than a single gigabit connection. Multiple USB 3.2 Gen 2 Type-A ports rated at 10Gb/s provide high-speed access to external drives and expansion enclosures. On the software side, QNAP's QTS operating system supports comprehensive backup solutions—including NetBak Replicator for Windows and Time Machine for macOS—along with remote access through MyQNAPCloud, multimedia streaming, and a wide ecosystem of installable apps for surveillance, virtualization, and more.
