I currently have a slow 5400 rpm drive in my laptop and I am looking at installing a 7200rpm drive.
The new drive is reported to be 100 times faster than the old drive. The traditional advice would say that a 7200rpm drive, drain laptop batteries faster, however if you compare the specifications this appears not to be the case is this correct? For example:
My current 5400rpm drive:
- spin up power: 4.5w
- seek power: 2.2w
- read/write: 1.9w
Replacement 7200rpm drive:
- seek power: 2.3w
- read/write: 2.1w
- spin up power: 5.5w
If I read this correctly, does this mean switching to a 7200rpm drive will have a negligible power drain impact? For those interested, I am comparing the following two drives:
