I just finished the process of adding 8 new Seagate Exos 20TB drives to my TrueNAS core system. This question has been asked a lot and it's known seagate drives are loader then most durring operation. Though i could not find anything related to a consistent "shudder" through all my new Exos drives. I have attached a audio clip in the link below. Have any of you come across this specific sound before.

The drives are in a Fractal Design 7 XL case with rubber bumpers in all trays. The case hold 9 WD Red's 12TB, and 8 Segate Exos 20TB. All 17 drives are connected to a SAS 9305-24i in IT mode. Running TrueNAS Core 13.0-U5.3

Can't say I have ever heard that before. Sounds scratchy, is that coming from the drives or something else? The shuddering is normalish but it sounds a bit off. I would do a long smart test to get a better answer if you are unsure. Ideally you should stress test all new drives.
