Home NAS Companion Measured: Hardware and Data Analysis with Quad-Core Routing Intranet Transmission Rate Breaking 2.5Gbps

As the demand for home data storage grows, the combination of NAS (Network Attached Storage) and high-performance routers becomes the core of home networking. Based on the measured data, combined with the hardware configuration and network environment, this paper analyzes how to achieve the internal network transmission rate to break through 2.5Gbps through the cooperation of quad-core router and NAS, and discusses its technical implementation and bottleneck.

1. Hardware Configuration and Network Architecture

1. The core role of quad-core router
to ZBT quad-Core Routing products for example, it is equipped with Qualcomm A53 quad-core 1.5GHz processor and 1GB of memory, supports Wi-Fi 7 protocol, and provides four 2.5G network ports. The multi-core processor can efficiently handle multi-device concurrent requests, and the actual measurement shows that it can stably carry 200 devices online, and the multi-device concurrent transmission rate can reach 2.35Gbps. The quad-core design significantly reduces data forwarding latency and ensures network stability under high load.

2. Performance Requirements for NAS Devices
equipped with dual 2.5G network ports, supports link aggregation (theoretical rate 5Gbps), and is equipped with Intel N100 quad-core processor and 8GB DDR5 memory. When it is transmitted through SMB protocol, the measured rate can reach 280 MB/s (about 2.24Gbps), which is close to the theoretical upper limit of 2.5G network port. In addition, the measured transmission rate reaches 283 MB/s (about 2.26Gbps) under 2.5G network, which verifies the decisive influence of hardware performance on the rate.

2. Measured Data and Rate Bottleneck Analysis

1. Network environment and protocol optimization

wired connection: Use super five or six network cables, with 2.5G switches, can reduce signal interference.

Wireless connection: Wi-Fi the wireless rate of 6/7 devices can reach more than 2000Mbps, the actual transmission is greatly affected by signal attenuation. It is recommended to use wired connection first.

2. Causes of rate bottlenecks

hard Drive Performance: The continuous reading and writing speed of mechanical hard disk is usually 180-200 MB/s. If NAS is not equipped with SSD cache or high-speed solid state disk, it will become the speed bottleneck. For example, a NAS that uses a mechanical hard disk may drop from 120 MB/s to 5 MB/s when transferring large files.

Protocol and Driver: Some NAS client software has a rate limit when it is transmitted within the LAN, and the limit needs to be bypassed through SMB or iSCSI protocol.

3. key technology to break through 2.5Gbps

1. Link aggregation and load balancing
by binding the dual 2.5G network ports of NAS with the dual 2.5G network ports of the router, the theoretical bandwidth can reach 5Gbps.

2. Co-optimization of processor and memory
the combination of quad-core processors (such as Intel N5105/N100) and more than 8GB of memory can efficiently handle high-load tasks such as data encryption and transcoding.

3. Heat dissipation and stability design
under long-term high-load operation, the heat dissipation capability of the router and NAS directly affects the rate stability.

4. User Deployment Recommendations

wiring scheme: Six types of network cables are preferred, at least one 2.5G network port is reserved for each room, and more than gigabit switches are deployed in weak current boxes.

Equipment selection: Select routers (such as Xiaomi BE6500 Pro) and NAS (such as Green Link DX4600) that support dual 2.5G ports, and enable link aggregation.

Hard disk collocation: NAS configures at least one SSD as cache or storage disk to improve the read and write performance of small files8.

5. Summary

through the cooperation of quad-core router and high-performance NAS, the home intranet can exceed the 2.5Gbps transmission rate, but the hardware performance, network protocol and environment need to be considered comprehensively. Excellent. In the future, with the popularity of Wi-Fi 7 and the decline in the cost of 10 Gigabit equipment, home networks will move towards a new stage of higher bandwidth and lower latency.
