Arch Becomes Very Slow When Doing I/O (copying/moving huge files)

Hi guy
I am facing a problem here, When i do large file transfer on local hard disk, or between local and external hard, arch becomes too slow and occasionally crashes.
Kernel:Linux knight 4.8.13-1-ARCH
any ideas?

is this has anything related to kernel parameters such as dirty_ratio and etc?

Post the journal section that covers a crash.

What filesystem do you have on your external hdd?

How do you transfer?
Terminal (command)?
UI based? Which one?

If UI based, then I'd try cp or mv to see if the same happens. Vice versa of course if you already using terminal programs.

Try the "ionice" command. Example:

ionice -c3 nice -n 13 cp srcfile destfile

yeah this has been standard linux behaviour for decades, best solution is to use small ssd for root and home and not use it for large transfers.
