How much does ‘power’ really cost.
Based on 0.11p / KWH (Kilowatt Hour) - the UK’s typical current domestic tariff, a 3KW electrical heater will set you back £0.33 per hour - simple really to calculate ? So use more efficient heating systems right - but what about your IT systems, especially those that need to run 24/7.
We have 8760 hours in each year, so any savings can be significant.
Let’s compare a low power Home Server (T7-HSA) and a recently launched ‘regular’ Home Server. Can you make real savings ?
Take the T7-HSA (single drive mode) @ 24W idle *
0.024KW x 8760 = 210KWH (or £23.13 / year to run it).
A similar, recently launched server (single drive) @ 52W in idle
0.052KW x 8760 = 455.5KWH (or £50.11 / year to run it)
It gets even more interesting as more drives are added.
The T7-HSA + 3x 1TB GP drives consumes 36W when idle
0.036KW x 8760 = 315KWH (or £34.69 / year to run it)
A similar, recently launched server + 3x HDDs, boasts 76W in idle
0.076 x 8760 = 665KWH (or £73.23 / year to run it)
Summary of savings to be made, low power vs standard home server:
1x HDD (Idle) SAVING £26.98 /year
4x HDD (Idle) SAVING £38.54 / year
4x HDD (full load) SAVING £46.00 / year **
Now if you are interested in saving costs, AND reducing your carbon footprint, remember power consumption is DIRECTLY related to carbon emissions.
Tree Hugging ?
So- you don’t have to be a tree hugger to think about making savings - just think about your bank balance too !
See what a ‘tree hugger’ (Paul :)) had to say about his Home Server SAVING experience - here.
(PS - Paul is not so cute as the girl in the picture !)
Paul indicated a saving of 220 W - that’s an annual saving of over £210.00 !!
Think about your bank balance, your carbon footprint - or our children ?
* PC Pro Magazine measured 20W in idle, we measured 24W
** Low power T7-HSA (full load + 4x HDDs) = 52W
Recent Home Server (full load + 4x HDDs) = 99W
