If you do want to power down HDD's, then I would say do it after maybe 4+ hours, don't power down after 15 minutes or something like that as your drive will not last long. Linux We have official Plex Media Server releases available for the following Linux Distributions: CentOS 7 or newer Debian 8 or newer Fedora 27 or newer SUSE 15 or newer Ubuntu 16.04 or newer FreeBSD Plex Media Server releases are available for FreeBSD 11.2 or newer. (SMART will tell you powered on hours of any drive. Plex Media Server supports macOS 10.11 El Capitan or newer. I have had drives run 24x7 for literally 8+ years solid - there are still zero issues with these drives but they were replaced as capacity per HDD in that period of time has obviously increased significantly !. Disks have fluid bearings, meaning they never wear out. If you are constantly stop/starting - then you will rapidly reduce the life/reliability of the disk vs keeping it spinning 24x7. Synology and Plex have the perfect solution for you In this vide. The 'stress' on any physical HDD is caused when it starts - both the thermal expansion (it getting hot/cold) and the power to start spinning the disk platters. For a home nas HDD hibernation is better as its not used most of the day, since the power consumption is reduced and the wear on the disc from it spinning constantly. They are designed to run 24/7 but doesnt mean they have to be. Im not sure where people get that they are better off working 24/7.

Sounds better than Plex at least which connects constantly to the internet and write to the log every one minute.
