QNAP vs BUFFALO NAS Showdown
Number of bays
The QNAP TS-673-4G offers eight drive bays, supporting six 2.5 or 3.5-inch drives plus two M.2 SSD slots. This allows for massive storage expansion and flexible RAID configurations. In contrast, the BUFFALO LinkStation 210 provides only one drive bay. While it includes a 2TB hard drive, you are limited to a single disk. If you need to store large media libraries or run multiple RAID levels for redundancy, the QNAP provides significantly more capacity and flexibility. The BUFFALO unit is strictly for small, basic storage needs.
RAM capacity
Memory plays a key role in handling multiple tasks and caching data. The QNAP TS-673-4G comes with 4GB of DDR4 RAM as standard, with an 8GB option available. This helps with virtualization, container apps, and faster file access. The BUFFALO LinkStation 210 does not list specific RAM specifications in its data. Without clear memory details, it is harder to assess its multitasking capability. For users running apps or heavy workloads, the QNAP’s specified RAM gives it a clear advantage in performance potential.
Network connectivity
Connection speed affects how fast you can transfer files across your network. The QNAP TS-673-4G includes four 1GbE LAN ports, allowing for link aggregation or load balancing to improve throughput. It also supports optional 10GbE expansion via PCIe cards. The BUFFALO LinkStation 210 is described as a value NAS but does not specify its network port speed or quantity in the provided data. Assuming standard single Gigabit Ethernet, the QNAP offers superior connectivity options and future-proofing for faster network speeds.
Form factor and size
Physical dimensions matter for placement in your home or office. The QNAP TS-673-4G is a substantial unit, measuring 11 inches in length, 10.4 inches in width, and 7.41 inches in height, weighing 12.3 pounds. It is designed for desktop placement with ample airflow. The BUFFALO LinkStation 210 is much smaller and lighter, measuring 9.45 inches in length, 3.31 inches in width, and 8.67 inches in height, weighing only 2.43 pounds. Its compact design makes it easier to hide on a shelf or in a tight space compared to the bulkier QNAP.
Target audience
