Does 3.5 HDD need 12V?
3.5″ hard drives require 12V and 5V for the motor and logic respectively. SATA ones may also require 3.3V for the logic. Most smaller laptop drives (2.5″) only require 5V and 3.3V. Some 2.5″ drives also require 12V.
Which uses more power SSD or HDD?
SSDs consume significantly less power than HDDs, which can point to longer battery life in laptops. SATA SSDs (larger ones that have a similar shape to HDDs) usually draw under 5W at most, and M.
How much power does HDD consume?
