You might be thinking of 2.5" laptop HDDs, which require one or two USB connections.
"So i heard"
As far as the adapter (wallwart or brick), it is necessary, as USB does not provide the 12v (typically yellow wire) that 3.5's need.
USB 3.0: 900mA, 5V, 4.5 watts
Also, 3.5'' HDD motors have very high start-up current requirements, they draw around ONE amp from the 5V line and around TWO amps from the 12V line for 3-6 seconds.
also, HDD's dont use much power to start up. they use about 15-18W to power on, the idle in the 8-12W range depending on the model. I've got a wall meter and tested many of them in an external enclosure.
and "some" to all hard drive use to power peak when they spin up, thats why most PSU don't like massive HDD arrays :-), i don't know why exactly but translatory inertia eats power .
( oh god i loved my 4x320GB IDE back the day, 350W PSU :laugh: )
best low power 3,5 HDs ive seen are the WD Green EADS line, taking 3-4W under idle/free spin, spindown is 1.2W and load only bumps to 5,6W
but hey time to upgrade my IDE!! IDE Usb 2.0 external Drive to USB 3.0 :D
WD greens may be low power, but they're as slow as a 2.5" drive.
Wall meters are useless in this case because they update too slowly as shown here.
interesting read on the hard drives power usage, but its not like i'm measuring at the back of the drive. i'm getting average results - and average power draw is what matters most.
Thanks.. :)
