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 ;)

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.
