  • OK. Science time. Somewhat arbitrary values used, the point is there is a amortization calculation, you’ll need to calculate your own with accurate input values.

    A PC drawing 100W 24/7 uses 877 kWh@0.15 $131.49 per year.

    A NAS drawing 25W 24/7 uses 219 kWh@0.15 $32.87 per year

    So, in this hypothetical case you “save” about $100/year on power costs running the NAS.

    Assuming a capacity equivalent NAS might cost $1200 then you’re better off using the PC you have rather than buying a NAS for 12 years.


    This ignores that the heat generated by the devices is desirable in winter so the higher heat output option has additional utility.
