> Synology recanted immediately

Is that correct? Looking at a common flagship model, the 4-Bay DS925+

and then the "Compatibility list" here https://www.synology.com/en-global/compatibility?search_by=d...

I see only Synology branded drives.

Synology do not make their own hard drives. They are rebadged.

It's true for HDDs. They don't maintain a list of compatible third-party HDDs, but you use them perfectly fine. No errors, drive health monitoring works, etc.

>Now, with the release of DSM 7.3, Synology has quietly walked the policy back. Third-party hard drives and 2.5-inch SATA SSDs can once again be used without triggering warning messages or reduced functionality. Drives from Seagate, WD, and others will work exactly as they did before—complete with full monitoring, alerts, and storage features.

NVMe SSDs are different.
