Unraid does a nice job of controlling HDD's energy consumption (and probably longevity) by spinning down (mechanical) hard drives when idle for a set period of time. Unfortunately the technique used by Unraid to spin down an HDD, true to the time of writing this, works only for ATA drives. If you have SCSI/SAS hard drives, these drives do not spin down (although the UI will indicate they do). The drives continue spinning 24x7, expanding the energy footprint of your Unraid server. Follo
