The WD20EARZ and the WD20EZRZ are not identical, although both belong to the WD Blue series with 2 TB capacity. The WD20EARZ uses CMR technology, as does the WD20EZRZ, but they are different model numbers, which may indicate differences in firmware or other specifications.
Since Synology does not have the WD20EARZ on the compatibility list and warns of data loss, it is risky to use this drive as a replacement in a RAID 1 array when a WD20EZRZ was originally intended. For RAID systems it is important to use exactly compatible drives to avoid data loss.
To summarise: The WD20EARZ is not identical to the WD20EZRZ and is not listed as compatible by Synology. Therefore, the WD20EARZ should not be used as a replacement disc in RAID-1 if the WD20EZRZ is the original drive.

No, unfortunately everything indicates that we will no longer be able to obtain it from our suppliers. We're very sorry about that. :(
Unfortunately not. Synology has very detailed compatibility lists: https://www.synology.com/en-us... Also generally speaking, the Blue series is more suitable for desktop PCs.
You can read about it in the Availability section.
These are two different recording methods, with hard disks behaving slightly differently depending on their intended use. It is therefore worth taking a look at this guide before buying:

Hello Christian,
You will get many answers to the question "what is the difference between CMR and SMR" if you search for it in Google, for example.

The WD Blue 4TB WD40EZAZ hard disk I bought at Digitec is an SMR drive. As far as I know, the WD40EZAZ is not available as a CMR drive.
Best regards

If it's not a new one, it's next to the article :)
You are right about that. I have reported this for correction and this will be dealt with as soon as possible. Thank you for pointing this out. :)
It needs a power and a sata cable to operate this HD. These are not supplied.
Power should normally be included with the power supply. The Sata cable was included with my mainboard. I did not have to order anything separately.

Your PC power supply should already have a SATA power connector. But you still need a SATA cable if you don't have one.

Good day
These hard drives are too big for notebooks, they need a 2.5 inch hard drive.
