[Windows Central]

Recent testing shows that contrary to popular belief, HDDs use less energy than SSDs in a wide range of scenarios.

What would also be useful to know is the energy required to complete a specific task.

eg to copy 250Gb of data to/from the drive (SSD and HDD).

The SSD would complete the task faster in many scenarios, so despite having a higher peak power requirement, would the total energy used to complete the task be lower (or not)?

A typical consumer will only pay an additional few bucks per year for power efficiency. The power consumption of an HDD/SSD/RAM is minuscule when compared to the power consumption of power-hungry components like the CPU/GPU/Mobo/etc... Performance/per watt and reliability are all that matter. Data centers need a throughput of 100TB/ps+++ I/O to efficiently make $_$. They have more important issues to worry about than the power bill.
