Could anyone point me to the direction, explaining the sudden drop in read performance during standard Ubuntu Disk benchmark after a certain time?
Is it the USB drive fault? Why the write performance doesn’t suffer then? Is it the system? What part exactly? Is it the benchmark itself? What is the correct one then?
EDIT: Forgot the details, that is SanDisk Extreme Go 64GB, Lenovo T450s and Ubuntu 17.04
