I moved from Synology to a Ugreen 4800 Plus running TrueNAS. It was louder than expected. I measured everything, printed a few mods, swapped the fan, and ended up with a NAS that is both quieter and cooler where it matters.

Backblaze’s ‘keep last version’ rule doesn’t delete old versions immediately. I found 21,000 extras and automated the cleanup with rclone.
