RobertLink after looking around I found it as a new way to grab money from people who are not into technical stuff.
What I think is, there has been a decrease in demand for flash drives. So they have come up with a plan to sell these pen drives. So they have installed Linux OS, which takes fewer resources (CPU, RAM) and can run on low-end computer machines. So it’s obvious it will run faster.
You can get one on your own for just 5 USD from amazon or somewhere and get a Linux distro for free from https://www.linux.org/pages/download/
So don’t waste your time and money on this stuff.
