Review on 💡 Rotated Design LED Light USB Flash Drives - SeeDete 16GB - 5 Pack (Gold, Black, Green, Red, Blue) - External Storage for Backup Data, Jump Drive, Memory Stick by Doug Small

I've used two of these joysticks before. I filled the first one with about 120,000 files of different sizes. I then filled out 3 files of about 20GB each. It took a whole day to copy all the files to the first one. Copying files to the second took about 6 hours. In the latter (faster) case, that's around 3 MB/s. That's about 1/40th the speed of my gigabit network connection, or 1/6th of my average Wi-Fi speed, or 1/4th of my average Internet download speed. All connections go outside of my computer. USB 2.0 has a theoretical top speed of 480Mbps, which is TWENTY TIMES the speed I've seen on these flash drives at their best! When copying a large number of files, these flash drives were several times slower. I did not expect a cheap drive to reach the theoretical maximum. I was hoping for maybe 60% of the theoretical maximum and expecting closer to 35%, but I didn't think I'd get 1% - 5%! Guess I'll give away the remaining 3 of these on Craigslist and buy some. still. I've bought other flash drives of the same price and capacity that worked much better, so I'd like to try my luck by buying a different brand.
