What's the suggested way to disable usb memory stick write caching in solus budgie? Most of my usb memory sticks are super slow and I want to track the progress when moving files to them. And if I try to shutdown the computer it doesn't work nicely because it's still writing behind the scene. Also while waiting after copy operation supposedly finished I cannot mount other partitions even those located on an internal nvme drive. I can image scenarios where the user would even want to cancel the copy operation all together. With write caching enabled that is not possible or is it?
PS: I have tried copying the large file with terminal command cp, nemo and cli midnight commander. All claim to have done the copy operation way too fast. So it must be write caching. Or am I missing something here?
