About NAS server running costs

A network-attached storage server runs for long periods. Hard-drive count, workload and sleep settings change its average draw.

Typical sizes: 30 W, 60 W, 100 W, 150 W.

How to spend less: Enable drive sleep where suitable and use efficient drives for always-on storage.

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average in Pennsylvania. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
