A two-to-four-bay NAS idles at 20–40 watts with drives spun down and more under load, around the clock. Enabling scheduled disk hibernation is the main way to keep a home NAS from costing more than the cloud storage it replaced.

How to lower the cost

  • Enable sleep after 15–20 minutes of idle — modern machines wake in seconds.
  • Anything always-on (servers, mining, chargers on strips) deserves a smart plug and a schedule.
  • Laptops do the same office work as desktops on a quarter of the power.
