It is absolutely important that the replacement disc also uses the CMR process, you have to be careful with the NAS discs, because there are some with SMR or CMR and yes this WD80EFZZ disc is CMR, so this technically matches the old CMR WD80EFAX discs :).
This is completely normal. This can be explained by the way an HDD works, because the read/write head of the HDD has to "jump" to reach the corresponding sectors. So if you "read" or "write" different things at the same time, the head will have to jump back and forth faster or more often. Defragmenting helps if the sectors of a file are not in a row ... then the clacking may become quieter. But the hard drive is still one of the quietest I have in my NAS.
Hello, yes, it should fit. In principle you can (since you have Raid 1) simply pull out 1 disc and put the new one in. Then you should see something about repair storage pool somewhere in the NAS storage manager. If you do this, the raid will be restored. This can take a few hours. It is best to simply wait about 24 hours. The new one will still be displayed with the capacity of the old one, don't get confused.
After the raid has been restored, do the same with the 2nd hard drive. Finally, expand the storage pool to 12Tb (also in the storage manager).
Yes, the Western Digital Red Plus 12 TB hard drive (WD120EFBX) has a standard SATA III (SATA 6Gb/s) connector that you can easily connect to your motherboard. This port is compatible with your ASUS TUF Gaming X670E-Plus Wifi motherboard.
So I don't know what Dreammaschine and Protect App are. I can only say that I have been using 4 of these HDDs in 24/7 operation in my Synology NAS since 2011, i.e. for 13 years, and in this time only one has failed, and that was only recently. So absolute top quality.
The 4TB variant is quieter, I have no experience with the 6TB, the 10TB are at least as loud as the 8TB, if not a little louder, larger HDDs are usually loud, as far as I know, the WD Pro are even louder, as are the equivalent Seagate drives. Unfortunately this is the case
When replacing, it is not so important to buy exactly the same disk, but it is important that all disks either use the CMR recording format, as with the WD80EFAX, or the SMR method. This WD80EFZZ can also use CMR, so it's a good match.
According to the specs, the old one should be able to do 150MB/s, you can also test it at home, only SSDs can do 750MB/s and more.

Difference to the new one will be SMR/CMR, there are already many threads about this, maybe this link will help you

Yes, the prices are established according to supply and demand, the suppliers and the availability of the goods, they are daily with us. They therefore vary very regularly, that's fine. However, you can contact customer service for a commercial gesture :)
Hoi - The hard disk supports any file system (be it SMB, AFP, EXT1234x, ZFS etc etc) - the NAS specifies which file system is (or can be) written. The NAS has - like any other system, e.g. like your PC or your MAC - an operating system installed (otherwise we could hardly communicate here together in text messages) and this operating system can read file systems...
A NAS does nothing else, but then additionally makes the disk space available to other systems - for whatever - e.g. for Time Machine.
Thus: YES, you can use the hard disk for TM - a NAS for this is quite practical, 2TB will not be enough for you over time, 2 hard disks that mirror each other make sense...
If you have more questions: fire away, I'll try to answer them for you - LG
