I've purchased two X20, 18Tb recertified drives from Server Part Deals and curious to the hive minds' thoughts on the performance. I have 4 X18, 18Tb drives which all have the following speed profile. Like, all 4 have this exact same line curve. Same speeds, same curve, everything, identical. Two drives were bought together and two other drives from different vendors at different times.

Is this anything to be concerned about? I started to preclear them in Unraid and one's currently sitting at 58% and the other is at 37% - Both started at the same time. I ran the tests a couple of times to make sure it wasn't a one-off. I made the mistake of running the X18's whilst dockers containers were running and noticed weird peaks and troughs until I turned them off.
