It' s a server drive, so I thought it would be noisier. There are reviews where it is written that it is quieter than the previous generation and that the noise is not so bad. Zial is not true. Due to the noise, the disk is unsuitable for operation in an apartment (our home), it is really extremely noisy (seek and deep hum).
price/capacity
for inactivity the noise is ok
the loudest disc I' ve ever had, you can hear it even in the other room when you close the door
nas is turned off because of the noise and I turn it on just at that moment when I need something. putting the disk to sleep doesn' t help, it turns it on even when I' m not accessing it, and the startup sound is really unbearable

After a failed experience with an external 18 TB HDD from WD, I decided to create my own backup storage. After a longer selection process, the Seagate Exos X20 20 TB was the best value for money product. After inserting it into the external box and mapping it, the stress test began in the form of uploading a number of files from several disks. Considering the primary purpose of the drive is for business use somewhere in a data center, I expected higher noise and heating. To my surprise, the opposite is true. Compared to the original external HDD from WD zero vibration and really incredibly quiet operation and little heating. I cannot evaluate the speed, the copying was done via an older PC and it depended on the electronics of the HDD box. The only thing I would like to point out is that everyone should check the real size of the disk before buying - 20 TB is actually 18.2 TB.

I replaced 2x Seagate Ironwolf pro 6TB in my Synology DS218+ NAS with 2xSeagate exos x20 20TB. The whole operation took about 24 hours. The Exos x20 20TB was not on the list of supported drives at the time of purchase. Everything seems to be fine and functional. Time will tell.
Functional on Synology DS218+

Being an electrical engineer, I am a fairly experienced user of similar goods.
I can't comment yet, I'm just putting it into operation.

Awesome fast platter drive. The capacity is very decent and it has CMR. I have it as an external and it's audible, but of course it's more of a server drive, so that's more of a comment, not a big negative.
