Overview

The QNAP TS-653D-4G is a 6-bay network attached storage device built around an Intel Celeron J4125 quad-core processor clocked at 2.0 GHz with burst speeds up to 2.7 GHz. With dual 2.5 Gigabit Ethernet ports, it delivers noticeably faster file transfers compared to standard gigabit NAS units, making it a practical upgrade for environments where large files are moved frequently. The unit ships diskless with six 3.5-inch drive bays, supporting both traditional hard drives and 2.5-inch SSDs, so you can configure storage capacity and RAID levels to match your specific requirements.

Beyond raw storage, the TS-653D-4G includes a PCIe Gen 2 expansion slot for adding 10GbE networking, M.2 SSD caching adapters, or wireless connectivity. An HDMI output with Intel HD Graphics 600 allows the NAS to double as a media player when connected to a display. The unit comes with 4GB of DDR4 memory, upgradeable to 8GB, and offers a mix of USB 3.2 Gen 1 and USB 2.0 ports for connecting external drives, UPS devices, or other peripherals. It runs QNAP's QTS operating system, providing access to a wide ecosystem of apps for backup, surveillance, virtualization, and file sharing.
