3.0 USB Speeds Going Up and Down

Recommended Posts

Posted · Original PosterOP

I am currently putting some files (around 5 GB) on a PNY 256GB 3.0 USB Thumb Drive. I don't know the exact specs on the thumb drive it self, but I am having an issue with the write speeds on it. Throughout the process the thumb drive's write speed will go up to around 80 mb/s one second and the next second it will go down to speeds as low as 5mb/s (or sometimes near or at 0mb/s) and then freeze for a few seconds only to rise back up to 80 mb/s for one second and will repeat the cycle. Could this be a software issue or just bad hardware? The picture attached shows the write speed graph.
