Customer Reviews more useful than 503 480 people have found this review helpful. EE for propeller heads out there, here are some electric EEhead For many discs I have bought 2 TB WD Caviar. I have had excellent results with them on my iMac. I use mainly for storing data when the fast recovery of data is not a consideration. I am more concerned to connect the USB-based platforms when I need data. However, they are also interested in them in terms of power, just because ... well, precisely because they are interested in them. Over the years, I worked my way up the scale storage capacity of the disk hard. How many of you, I was rather shocked at the way these older models that warm. I swear, you can fry an egg on some of them. I never felt comfortable with their life, probably for fear of being burned. Fortunately, no one has done. When the Caviar Black product line coming out (1 TB was when I won the first release), I was quite fascinated by the power reduction claimed in the electronics industry, heat is the greatest enemy of the components. Usually halve every 10 degrees C temperature increase life of components. The Caviar feel like a way to get a more reliable drive, if the energy saving numbers actually panned out. I took one of the drives in to work where I want to test gear at my disposal. Especially I have some very good Tektronix current probes, which allows me to measure DC and AC power. I built a little cable that leads me to +12 V and +5 V lines, so that my current probes to the wires can pinch, so to measure power consumption. I connected the two power leads for power supplies, so I could also vary, the two voltages. This way I can just see and measure current consumption of the drive, drive I exercise. I get more accurate measurements in this way you can use a simple watt-meter that you can rarely see what the fractional watt Because I can not (actually, do not know how) scale embedding images in this review, all I can do to verbally describe my observations. My tests are far from complete, but they give you a good idea of ​​how much power these devices draw, and when they attract. * If the disc just sits there doing nothing but spinning is +12 V 0.24A power consumption +5 V and the drain is 0.13A. It comes down to 4.2 watts in idle. I have not previously measured, high power devices, but I'm willing to bet the Caviar Green takes half the power of traditional hard drives. I would not be surprised if 1 / 3 of power. * If a surge, the second stop drawing all power supplies. It is a convenient way to power devices on and off. I would suggest turning off the power to the +5 V rail loop to turn off the +5 V supply with a single PFET is easier than for the +12 V rail * When the device is first turned on, +5 V pull a nearly constant 500 -600 mA. During a 12 V ramp from 200 mA to 600 mA and continued until after about 10 seconds, so when the plant is fully operational. At this point, turning +12 V peak current drops to a minimum), current 0.24A. It does not vary much after that, regardless of disk activity (erase, write, read, etc..) On the other hand, +5 V stream is recorded. It's pretty clear that the servo head is driven from power at +5 V and +12 V. It is difficult to describe verbally the current 5 V, but I will say that the average flow during head movement activities is about 400 mA. When there is no activity, the current is approximately +5 V 0.13A. When the drive is doing what he does, then go down to 4.2 watts in standby, I mentioned above. If you are a designer food, you should be aware that these currents are DC I quote averages are, and you have a "hash" of alternating currents, which result from the list of averages, I +5 V power a hash of about 300mA PP and chopping 12 V pp can be 400mA * I.
