You need to have pretty tight supply chains if you’re going to support warranty claims on something as consumable as disks. I don’t know who supplies their HDD and SSDs, but you’d want the relationship and traceability to be pretty robust.

Syno have always been a software company first, a hardware company second, and a storage media company last. It makes sense to try and control the full vertical, but they just don’t have enough clout to compete against the big enterprise companies.

I honestly believe the disk whitelisting thing was part of an attempt to overvalue the company in preparation for a sale.
