QNAP's four-bay TS-451D2 is built around multimedia output: a single HDMI 2.0 port drives a 4K@60Hz display directly from the NAS for HD Station and Linux Station. Networking is handled by two Gigabit Ethernet jacks (bondable via Link Aggregation), and there are four USB 3.2 Gen 1 (5 Gbps) Type-A ports — one on the front with a one-touch copy button. Note the LAN is 1GbE, not 2.5GbE, so for faster networking you would add a USB or PCIe adapter; the everyday cables that matter are an HDMI lead and two Ethernet leads.
