Review on Aluminum USB 3.0 Hub - Ultra Slim 4-Port, Compatible with Mac Pro/Mini, Microsoft Surface Pro, Dell XPS 15, Xbox ONE by Tyler Kota

Summary: You have a laptop at work that only has three USB-A ports, so you want to expand it. Details: The main desktop computer is a Dell XPS 8920. The system drive is a 250GB SSD. Two more hard drives for data, 1.0 TB and 6.0 TB. External USB ports: USB-C 3.1 (rear), USB-A 3.1 (rear), USB-A 3.0 (front). The difference in transfer speed between front (3.0) and rear (3.1) was negligible. Test Method: The test program I use is ATTO Disk Benchmark (free software). I tried several different ones and settled on this one because the resulting image was relatively easy to compare to other results. When evaluating the results, I paid particular attention to the transfer speed of files from 1 MB. As shown in the attached screenshots, there is no slowdown between a direct connection and via a hub. So there's no slowdown from the hub. Recommendation: Get a good free speed tester. Pros: Good fit and finish; a metal body (not plastic) that dissipates heat well; green LED indicator. Disadvantages: none. Conclusion: I would recommend this basic 4-port USB-A to anyone who needs more ports. .com/gp/product/B07MQYVZCM
