Inventory includes: Windows 10 Desktop, Windows 10 laptop, MacBook Air (Catalina), MacBook Air M1 Big Sur). NAS use for centralized storage for disaster recovery. I have 1TB OneDrive storage and 2TB iDrive storage. I would like to retain both versions of APFS, Catalina and Big Sur along with NTFS on Windows 10 machines. I would also like a local port on the NAS to attach Thunderbolt / USB to provide 20 Gbps for backup of NAS.
You could consider Qnap Thunderbolt NAS options such as TVS-472XT. You can then connect directly and via the Ethernet at the same time.
Qnap QSYNC is a Dropbox and OneDrive alternative with better functionality and no limits and subscription. You can still link your existing cloud providers with your NAS and access them all fro one place.
There is no other Brand that will offer this functionality and quality of apps.
I hope this helps.
