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.

>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.
