Review on Besgoods 4-Pack 6ft USB 3.0 Extension Cable - Braided USB Extender Cord for Hard Drive, Keyboard, Mouse, USB Flash Drive, Printer - A Male to Female USB 3 Extension - Black by Victor Ceja

To test the performance of these extension cables, I ran a series of benchmark tests using a Corsair Voyager GTX (very fast) USB 3.0 drive. As a base, I first tested a drive connected directly to my computer, which gave the first results (459 MB/s sequential read, 86 MB/s random read, 178 MB/s sequential write, 17 MB/s sequential random behavior). Entry). . For those who are more interested in voltages, 4.97V, 0.331A were top values in the test. I then used one of the USB 3.0 extension cables and ran the test again. There was some loss of performance, but compared to other cables I've tried, I find this a VERY POSITIVE result. (428MB/s sequential read, 80MB/s random read, 180MB/s sequential write, 17MB/s random write). For those who are more interested in voltages, 4.95V, 0.323A were top values in the test. Conclusion: These are good extension cords. The braided sleeve looks well made. The female connection is VERY tight, if you plan on disconnecting and reconnecting this cable frequently I suspect it will be annoying. If you're looking for a USB 3 extension cable for a keyboard, mouse, scanner/printer, etc., this is probably what you're looking for, and the solid connection is actually a plus. Bonus test: Because they come in a 4-pack. What happens if I use all four together?. Wow, the drive worked, but performance dropped (43MB/s sequential read, 29MB/s random read, 43MB/s sequential write, 12MB/s random write). For those who are more interested in voltages, 4.95V, 0.212A were top values in the test. This should NOT be taken as a negative result. Just remember that the longer the extension, the lower the performance.
