Electricity usage

[Man-wai Chang ToDie]

How much electricity could I save from replacing a 3.5" 7200rpm hard
disk with a 2.5" 5400rpm one?

Not a lot I expect.

**** all with a modern desktop system.

It would take years to pay for the drive change even if the
system is on 24/7 and you'd be a lot better off just getting
the system to sleep when it isnt being used, that would
save much more if thats feasible.

The platter is smaller, so the motor is smaller... so ....

Depends on your usage pattern and the disks in question.
Just read the datasheets of the disks.

Sure, but that effect is swamped by the other power use of the rest of the system.

In Australia you would save about $1 per year (9kWh) for every watt of
reduction in power consumption, assuming your drive spun continuously
during that time.
