I noticed heavy usage of my drive, caused by mconnect

% { strace mconnect } 2>&1| grep --line-buffered .cache/mconnect/devices....... | pv >/dev/null
30,0KiB 0:00:01 [30,0KiB/s] [  <=>                                                                                                                 ]
