Synology HDD db is a shell script that adds unsupported storage drives to a Synology NAS device's compatible drive database.
The tool solves the problem of hardware compatibility restrictions that Synology imposes on which drives can be used in its NAS systems. It works by modifying the internal drive compatibility databases on Synology devices running DSM 6 or DSM 7, allowing users to install SATA and SAS HDDs, SSDs, and NVMe M.2 drives that would otherwise be rejected by the system. The script can target the main NAS database as well as expansion unit and M.2 PCIe card databases. It includes a restore function to revert all modifications if needed.
This tool is suited for Synology NAS owners who have drives they want to use but find them blocked by the manufacturer's compatibility checks. It works across multiple DSM versions and supports recent hardware models. The script is particularly useful for users who have purchased third-party drives or are upgrading storage with non-approved components and want to avoid the artificial restrictions Synology places on drive selection.
The project maintains active engagement with its user base, with almost all reported issues coming from adopters in the field rather than the core team, demonstrating substantial real-world usage. Maintainers respond to new issues and pull requests within a day. Work tracked in the issue system centers on bug fixes, feature enhancements, and documentation improvements.
