External Hard Drive Energy Calculator (Cost and kWh Usage)

External hard drives are an essential device for anyone who needs to store large amounts of data, such as documents, videos, music, and pictures. They offer a convenient way to store and access this data, especially when compared to the limitations of internal hard drives. However, with the increased use of technology comes increased energy consumption, and therefore, it is important to take a closer look at the energy consumption and costs of using an external hard drive.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

The energy consumption of an external hard drive varies depending on the model and usage. Typically, the power usage for an external hard drive ranges from 1 watt to 10 watts. This means that if you have the device plugged in for 24 hours, it would consume an average of 24 watt-hours per day, or 720 watt-hours per month. This might not seem like much, but over time, it can add up to a significant amount.

It is important to note that some external hard drives come with power-saving features, such as automatic shut-off when not in use. This can help reduce energy consumption and save you money on your energy bills.

Importance and Relevance

The energy consumption of electronic devices is a growing concern in our modern world. As more and more people rely on technology for both personal and professional needs, the energy consumption of these devices can have a significant impact on the environment. In addition, the cost of energy consumption can also impact people’s finances, making it important to be aware of the energy usage of devices like external hard drives.

Cost in Dollars of Energy Usage

To calculate the cost of energy usage for an external hard drive, you need to know the wattage of your device, as well as the cost of energy in your area. Assuming a wattage of 1 and an energy cost of $0.12 per kilowatt-hour, the cost of using an external hard drive for a day, a month, and a year is as follows:

  • Daily cost: 1 watt x 24 hours x $0.12/kWh = $0.003/day
  • Monthly cost: 1 watt x 720 hours x $0.12/kWh = $0.86/month
  • Yearly cost: 1 watt x 8,760 hours x $0.12/kWh = $10.51/year

Money Saving Tips

Here are some tips to help you save money on energy costs when using an external hard drive:

  • Use a power strip or surge protector to turn off the device when not in use
  • Invest in an external hard drive with power-saving features
  • Opt for a solid-state drive (SSD) instead of a traditional hard drive, as SSDs tend to use less power
  • Consider cloud storage as an alternative to physical storage devices, as it can be more energy-efficient and cost-effective in the long run.

By following these tips, you can reduce your energy consumption and save money on your energy bills, while still enjoying the benefits of using an external hard drive.
