I currently own an 20TB Home Duo with a faulty drive that needs replacement.
Currently the unit has 2 of WD100EFAX drives installed with one drive making clicking noises.
I have found a local vendor who can sell new WD101EFBX and wanted to know if these drives are compatible with the Duo before I commit to purchase.
The WD My Cloud Home comes in 2TB, 3TB, 4TB, 6TB, and 8TB capacities. For users who want more storage or greater security, they can opt for the My Cloud Home Duo . These come with two drives and can be configured in either RAID 0 or RAID 1, depending on your needs.
I know it’s not the best reference but this site has your hard drive model in the Home Duo so I think it should work.
Please see the following articles that may assist in your question:

If further assistance is needed, please open a case with our support team at the following:
Installed an WD101EFBX with an WD100EFAX and it seems to be working fine.
Initially I got the LED heartbeat pulse after the install which indicates the drives where synchronising the raid 1 configuration. Now I am getting a solid LED and the drive is accessible.
I wish WD would include some basic diagnostic or status tools via an app so I can check the general health of the system.
Just hope WD doesn’t do something malicious on the next firmware update and brick the device because it has two different spec WD Red Drives.
Absolutely. We shouldnt have to depend on counting lights and going, “There are 4 lights!”, to determine if the drives are syncing and working.
