We purchased two of these drives to expand the capacity of our home server. We were worried about noise and cooling issues, but both turned out well. The drives are quiet, only the head exposure is sometimes quite loud (under load), the temperature is within reasonable limits (there are a total of 4 drives in the server).
quiet, you can stand in the same room with it
Temperature around 40 °C in a standard PC case
came wrapped in bubble wrap and a bubble envelope
crazy price, but that's not the problem of the disc

When I was looking for a replacement for the low-speed drives in my home NAS, which are not manufactured in capacities above 8 TB, I was quite worried about noise. Ironwolf Pro surprised me though: in idle, it is practically not audible at all until I put my ear directly to the NAS, when reading/writing it is a little noisier than the original WD Red, but not fundamentally disturbing. I consider the 20 TB version to be a happy medium - high capacity and reliable conventional writing without SMR/HAMR.
Temperatures 30° - 40° C depending on load
virtually inaudible at idle
relatively quiet when reading/writing
filled with helium
CMR notation technology
20 TB capacity (10 physical platters)
arrived lightly tapped on the top aluminium cover

If you need a NAS drive, this is a good choice. The pro version has a higher (compared to the base IronWolf series) RPM, so it is noticeably faster. The drive is more robust overall and also comes with a 5-year warranty.
Within the HDD fast.
Solid reliability. They always last almost 5 years without any problems. Defective sectors are rare.
Good price.
It works well in my 47TB disk array.

Value for money, durability is a question, too early to evaluate, compatibility with Synology ds225 is ok

I'm not an expert, I just have a lot of data, so I needed to insure its loss, to free up space on my main drive. Anyway, I received the drive, plugged it in and it works perfectly. Since I didn't need it for a server but for my own desktop computer, I was a bit surprised by the slightly loud sharp sound I hear whenever this large hard drive boots up. But it's rare.

The drive is high quality and fast, the capacity is great, and it's pretty much silent (except for the head rattling). But what is incomprehensible and unacceptable is the state in which the disc arrived. The top metal cover of the disc is visibly battered in several places and the disc must have suffered some pretty solid bumps in transit. And the fact that the disc only comes in an anti-static bag doesn't help either. The drive itself works, but it's hard to say what effect the scratches will have on the operation and life of the drive. I'm beginning to understand why Synology wants to control what its customers put in their NASes as drives. Such treatment of such delicate and expensive goods is incomprehensible and inexcusable by the alza or its suppliers.
The top aluminium cover of the disc is visibly battered
