The most interesting part of that output is here.
Once per hour on average drive performs head parking, which cannot
explain what you're seeing.

For the comparison, this is what I consider "normal" (head parking
completely disabled):

  4 Start_Stop_Count        0x0032   100   100   000    Old_age   Always -       57
  9 Power_On_Hours          0x0032   050   050   000    Old_age   Always -       20037
 12 Power_Cycle_Count       0x0032   100   100   000    Old_age   Always -       57
192 Power-Off_Retract_Count 0x0032   100   100   000    Old_age   Always -       35
193 Load_Cycle_Count        0x0032   100   100   000    Old_age   Always -       3130
