PESolution · 7 Nov 2011 at 20:26

So im looking into getting a nas server like this:

But im sturggling to work out in reality if i have it on 24/7 - say downloading for an hour a night, and streaming for a couple of hours every other day, how much *about* it would come to?

Apparently its 17.6 watts, so what does that come to on an average uk tarriff 24/7?

1.21 GIGAWATTS!

17.6 watts? Naff all.

17.6w x 24h = 422.4w/day
422.4 x 7d = 2956.8w/week
2956.8 x 52w = 153753.6w/year
153753.6 / 12 = 12812.8w/per calendar month

Assuming each kw costs £0.14.

£0.06/day
£0.41/week
£21.53/year
£1.79/per calendar month.

A month? No it doesn't.

A year.

Dunks · 7 Nov 2011 at 20:52

If it drew 500W constantly 24/7 for a year then yeah, but that's quite unlikely

No it doesn't. Unless you're running at full chat 24/7.

Depends how many drives it has, how often you read and write, and how efficient its power supply is.

Answer - same length as a piece of string. Your average hdd can consume more than double when its reading writing as opposed to idling.

tbh i wouldnt worry about it, if its just for general home use then its not gonna cost anything significant enough to worry about.

If its just for file serving in the home, you could maybe slower "green" drives in it rather than standard 7200 rpm ones.

Get a plug in electricity cost meter from a well known electronics supplier (you can probably guess the name, forum won't let me post it).

Watts divided by 1000. Multiply by number of hours it's on per day. multiply that by the number of days (365.25/12). Multiply that by the price per unit of electricity.

So for 20w, 24hrs at 14p/unit we have:

(20/1000)x24x(365.25/12)x0.14= £2.05 per month.

Had a ReadyNAS Duo running for near 2 years and it hasn't broke me. Electricity for PC gear costs bog all compared to most "living expenses". Who here thinks nothing of buying a coffee in a trendy coffee shop at lunch/on the way to work? I blown £40 a month some weeks in latte alone

Corrected, sorry but I can't stand it when people don't know the difference between a Watt and a Watt hour.

Edit:
If you have electric heating that isn't off peak it's free to run in the winter, you'd also be mad.

That isn't a living expense, it's a smugness tax
