Load Hard Drives

[Enquiries]

I purchased a Synology DS923 and 2 Ironwolf Pro 20TB Hard drives. The hard drives are very noisy. (it kinda sounds like small animals are moving furniture). I was thinking that I should swap these hard drives for 2 - 12 TB. Do I have any other options? Can use the 20TB hard drives in the NAS and have them not run all the time?

Also... I really like your YouTube channel and living in Seattle, I can relate to your dislike seagulls
