+**DSM 7.3** has removed the many of the restrictions that were in DSM 7.2.2 for 2025 Plus models.

+See https://kb.synology.com/en-global/DSM/tutorial/Drive_compatibility_policies
+
+The restrictions that remain in DSM 7.3 for 2025 Plus models are: 
+1. You cannot create a cache or volume on 3rd party NVMe drives.
+2. You still see lots of warnings in storage manager when using unverified 3rd party drives.
+
+Both 1 and 2 can be solved with [Synology HDD db](https://github.com/007revad/Synology_HDD_db)

 You can't download Synology HDD db to a volume because you've just deleted your storage pool. So you'd first need to download Synology HDD db to a system folder and run it from there.
