Or does the hard drive go to sleep when idle? Long gone are the days when Intel and AMD were locked in an arms race for higher clock speeds and big performance gains at the expense of everything else.Today CPU manufacturers are more interested in lowering CPU power consumption while achieving similar or improved performance. Optical drives consume just 1.5 to 5 Watts of power during idle, so they add very little to the total power consumption of PC components. The initial jolt of power needed to spin the internal discs can cause the Pi to reset. This is a Western Digital 3.5 USB 2.0 External Drive. Which is .025 Kw.

The reduced standby power level meets requirements for the forthcoming European Union?s EuP (Energy Using Products) Directive for Standby Regulation, effective January 2010. P.S. The ‘unstable’ 5V 2.5A i have can only handle a 314GB WD Pi Drive and that’s it. To contrast, an SSD that is 5V 1000mA and runs for about 10 minutes for every hour of operation. When calculating power consumption of PC components, most consumers fail to factor in case fan power usage. I also was curious about the power consumption of modern 2.5" drives but didn't found any good articles except this discussion and THG article about 500 Gb drives (mentioned in the question). Idle Power Draw - Computer is booted into a clean installation of Windows and left to idle (power savings turned off). That being said, solid state drives still consume less power than 3.5" hard disk drives (plus they are magnitudes faster and less vulnerable to physical damage). ... start up off of 5 watts or less. For archival purposes here is an excerpt from the specification. Just got curious about how much power to drive this external drive as I'm using it as a backup for my NAS, which is usually open 24 hours a day. A stick of 4 GB DDR3 RAM will draw about the same amount of power as a stick of 8 GB DDR3 RAM (assuming that they have the same clock speed). I'm assuming that my laptop's USB doesn't have enough power to support external hard drives. @Michael Karas I have such USB tester. How to find out if a preprint has been already published. After some further googling I've found official specification of Seagate Barracuda 2.5" 3/4/5 Tb drives for spinning up/reading/writing/sleep modes.
