I’m creating a script to monitor my hard drives temperatures (just for fun) in a NAS. For this I’m using hddtemp. This porgram polls the hard drives S.M.A.R.T. data for the last update temperature.
I notice the first call to hddtemp takes a litte while to complete. Probably because the devices are inactive. Subsequent calls to hddtemp are much faster.
Does reading disk S.M.A.R.T. data (e.g. using hddtemp) too often strain the disk or affect its performance in any way?
