Any idea of the energy consumption of a Buffalo with a 2.5” and with a 3.5” disk, idle/active?
Considering energy costs ranging 15-25 ct/kWh thats something to also consider.
Example calculation:
A device using 20W constantly throughout 1 year will consume 175 kWh total electricity. Thats 35 EUR/year assuming 20 ct/kWh.
A very low energy device using only 10W would cost you only 18 EUR and a PC with 60W almost 100 bucks.
Not to speak of CO2 balance and other problems with energy consumption.
