hard drive
At the current prices in my locale, it works out that the HDD costs about 62 cents per month and the SSD costs 0.4 cents per month to operate. The SSD saves $7.40 per year in electric costs if left on with load 24/7, but if power management is used, it would likely be more like $2. The math: 9.47¢/kWh=0.00947¢/Wh.
