To understand the yearly impact of a 4TB hard drive’s power consumption, it is beneficial to calculate its annual power usage in kilowatt-hours (kWh). This is the standard measurement used by utility companies. Assuming an average consumption:
- Idle state (12 hours/day):
6 watts × 12 hours × 365 days = 21.9 kWh - Active state (4 hours/day):
12 watts × 4 hours × 365 days = 17.5 kWh - Sleep state (8 hours/day):
2 watts × 8 hours × 365 days = 5.8 kWh
Total annual consumption = 21.9 kWh + 17.5 kWh + 5.8 kWh = 45.2 kWh per year.
Using an average electricity cost of $0.13 per kWh, the total annual cost of running a 4TB hard drive would be approximately $5.88.
