- mrb 15y agoVery low. I estimate the power consumption at the wall to be ~400W. That's $29/month at $0.10/kWh. Host this in a datacenter with a non-remarkable PUE of 1.5, and that's $43.5/month including cooling. * 45 x Hitachi HDS5C3030ALA630 drives, 4.8W each (average when idle), a tiny bit more when seeking so let's round to 5W.
