Which 2.5' HDD (not SSD!) to choose with a minimum startup current?

Question

Hard disks

Which 2.5' HDD (not SSD!) with minimum startup current should I choose for an external Mobile Rack without additional power supply (USB 2.x only)?

Answer 1

as a result of studying the issue:
- on the label of the HDD itself, voltage and current are indicated
- in the reviews and / or technical specifications, look at spinup current (thanks to user John Smith!), average power requirement, etc.
