Used it for clean installation of an operating system. I clearly witnessed below average read and write speeds on this pendrive. It is mediocre.
It will just give you and average of two to three mbps of write speed and read speed is just above average.
Beginners would have no problem using this anyway.
But I would not refer it to power hungry users who install a lot of games on pendrivers to use it on low end systems.
Thank you!
