@ Charles Polisher

yes, seems that avgrq-sz does provide the info I needed, thanks for
pointing that out!

@ Keith

I am not sure if blktrace can monitor which files being written to
disk or if it is the best tool for that.
But you could check out the inotify-tools (iwatch and related) which
go on that directions.
An example usage is here

or iwatch
