2nd drive has almost 4x as much power-on time than the first one. My guess
would be that it accumulated all that write usage back before you put it in=
to
this RAID1.

If you want to ensure the RAID1 usage is even, record the SMART data you ha=
ve
now, and compare to the readings you will have a month later.
