Your DS2422 should technically support the 18TB HC550 and 20TB HC560 drives, as they are enterprise-grade SATA drives. However, Synology has been pushing their own branded drives and has limited official compatibility for third-party HDDs, especially on enterprise models like the DS2422.
Key Considerations:
Synology’s Compatibility List: The DS2422 officially supports 18TB and 20TB Ultrastar DC HC550/HC560 drives in some regions but is not explicitly listed for all.
Drive Recognition: While the drives will likely work, Synology DSM may show "Unverified Drive" warnings, and future updates could introduce restrictions.
Workarounds: Users have bypassed compatibility warnings by modifying DSM, but this is not officially supported and could impact warranties.
Alternative Options:
QNAP: More flexible with third-party drives, supports ZFS (QuTS Hero) if you prefer data integrity features.
TrueNAS: A DIY NAS using a ZFS-based OS might give you full control without vendor lock-in.
If your IT shop has firsthand experience with issues, it might be worth testing one DS2422 before committing to both.
