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.

Happy hour over again. It was probably more of a happy minute ;)

Hello Roger, I've had a quick look. Here it looks like you would get the same: WD Red Plus (8 TB, 3.5", CMR) ciao.

have a look at the price development, it also explains why the prices are the way they are

Can't say, at the time I bought mine the 14 was either not yet available or it was (much) more expensive. I do not recall.

Hello Should work, normally the NAS "regulates" this itself. The lowest RPM wins. Let us know which NAS and if it worked. Greetings

A year ago, there was a fair amount of negative press regarding WD Red hard drives because they reported incorrect RPM values to the SMART tools (programmes that read technical metadata from the hard drives). The new models fix these problems. https://www.heise.de/news/Nach-Kritik-an-5400-RPM-Class-Western-Digital-bringt-neue-WD-Red-Plus-HDDs-4954777.html

The question is not easy to answer. It depends on what kind of RAID you use.
