Dashcam write issue solved with ext4

[pereiks]

I was having issues with dashcam always complaining about slow usb drive write speed. Write speed of my flash stick is ~20MB/s on usb3 so i couldn't figure out how that can be a problem. Anyway, started experimenting with different file systems and turned out that on ext4 dashcam stops complaining about write speed. Hope that helps for folks who are still experiencing issue on a usb stick with good write speed.
