Start for freeThe Surprising Truth About 5 Gigabit Ethernet USB Adapters
When we embarked on a journey to test 5 Gigabit Ethernet USB 3.1 Gen 1 adapters, we expected performance to be a straightforward affair. However, the reality was far from it. In this comprehensive review, we dive into the details of our findings and guide you through selecting the best adapter for your needs.
Background and Testing Motivation
Our team at STH decided to explore the realm of Ethernet adapters, initially focusing on 2.5 Gigabit options before venturing into 5 Gigabit Ethernet adapters. Our goal was to enhance the networking capabilities of our Project Tiny Mini Micro nodes and other devices with limited networking options. The adapters tested included models from Trendnet, StarTech, and Sabrent, with a potential QNAP unit pending future review.
Initial Findings
Contrary to expectations, none of the adapters delivered the 5 Gigabit per second performance as advertised. Despite linking up at the correct speed, data transfer rates to the host system were significantly lower, peaking at around 3.4 to 3.5 Gigabits per second. This discrepancy is attributed to the limitations imposed by the USB 3.1 Gen1 interface, which caps at 5 Gigabits per second, not accounting for overheads.
Detailed Adapter Analysis
-
Trendnet TUC-ET5G: This adapter, while initially promising, exhibited stability issues across multiple systems. It required specific Trendnet drivers, which were outdated and flagged by Windows security features. High CPU utilization and frequent disconnections further marred its reliability, leading to its low rating on our site.
-
StarTech US5GA30: Made predominantly of plastic, this adapter performed as expected without notable issues. However, its construction and price point raised questions about its value, especially when compared to more robust options.
-
Sabrent NTS-5G: Standing out for its metal construction and dual USB cable options (Type-C to Type-C and Type-C to Type-A), the Sabrent adapter offered the best build quality among the three. Its performance was on par with the StarTech unit but at a significantly lower price point.
Our Recommendations
Based on our extensive testing, the Sabrent NTS-5G emerges as the clear winner, offering the best value and versatility. The Trendnet adapter’s stability issues and the StarTech’s higher price for similar performance make the Sabrent unit the most appealing option for users seeking to upgrade their network speeds.
Final Thoughts
While the allure of 5 Gigabit Ethernet speeds is strong, the practical limitations of USB 3.1 Gen 1 technology mean that users should temper their expectations. The real-world performance of these adapters is closer to 3.5 Gigabits per second, which, while an improvement over traditional Gigabit Ethernet, falls short of the advertised speeds. When choosing an adapter, consider not just the potential speed gains but also the build quality, driver support, and price to find the best option for your needs.
