Synology Hybrid RAID (SHR) is a proprietary system that combines multiple disk sizes into one volume, using Linux MD RAID (for redundancy) and LVM (for flexible space allocation). Unlike traditional RAID 5 or RAID 1, SHR can use mismatched drives.
Elias didn't cheer. He didn't pump his fist. He immediately opened his backup software and watched the progress bar crawl toward 100%. He had looked into the data-loss void, and for once, the void had blinked first.
Best for: Forums, Reddit (r/synology, r/sysadmin), or tech community groups.
Synology’s SHR offers great flexibility, but it locks you into an ecosystem. Always maintain the 3-2-1 backup rule . A RAID array (even a redundant one) is not a backup; it is availability. When availability fails, you need a backup, not just a recovery tool.
→ Rebuild with confidence. If no backup → Clone each disk first with ddrescue , then attempt manual assembly on Linux. Avoid writing anything to the original disks until data is safe.
Before attempting software repairs, verify physical health.
