Six years ago my box shit the fan. Synology could have recovered it for me, but they insisted I "upgraded" to their newest box. That was when I realized that I would never buy from them again. Thank goodness their hybrid raid is at least MDRAID.

Honestly, old server equipment is more powerful than most of these RAID boxes. The only caveat there is that old server equipment is often not quiet, and rather power hungry (200W at idle with no power save mode).
