The drive surface temperature is low, and very similar across the tested devices.
Man Western Digital its on the ball for a while... Hope they keep it up.
I think power efficiency have gone way beyond practical. Take the 2TB WD drive running it at max for 24hr per day for 1 year. You get a total usage of 6.9 x 24 x 365 / 1000 = 63kW which converts to $9 electricity for 1 year. Comparing this to insane graphics card consumption for 300, 400, 500 even 1000W+ systems. I don't see why Tom's keep on telling us HDD are going green when it really matters little in the overall PC consumption.
When I read the title I was excited, after checking out the roundup I was a little bit disappointed. I'm missing the Seagate Barracuda LP drive, which is also available in 1.5TB. Why don't you guys put this drive in the roundup as well?
The images with the electrical boards are misplaced. It makes the Samsung look like a carefully assembled hard drive...
The only reason for buying a "Green" hard drive is not lower power consumption. I mean... It's not much of a difference. It is a very large percentage, but a very small number.So you're not going to save the Planet with Green drives, unless you buy them by the hundreds for big farms. I think they should sell regular drives as Green ones, and when someone purchases one, they should plant a few trees somewhere on the Planet in their name...For me, the only good reason for buying a Green drive would be to use it for storage because the 5400 RPM should translate into better reliability (but that's not proven yet).
the best good points of these hdd's are that they are reasonably cool, low power requirement for htpc's with a small psu and reasonably quiet. That makes them very good in the htpc market and that is where they are best for.Yes you can use them in your regular pc as well off course but that is not the main market. I think the seagate wasn't available at the moment they started testing the disks and that is why it is not included, or they didn't got one from seagate on time.
I'm all for efficiency, but I hope people don't think that getting a "green" hard drive and saving three watts is going to "save the planet."
Tom's, thanks for doing an article with some power/temp/noise statistics -- it's great to see those numbers, when they are usually glossed over or ignored.Now if we could just get some stats on Video Cards, or get the graphics manufacturers to produce even just 1 model of a smaller, cooler, quieter card rather than the ever-bigger, insanely hot ones.-and to the people who said these drives won't make a difference. Yes, taken alone they won't, but that's the same with pretty much everything. The point is, it's good to see the direction of innovation headed in the low-power/temp direction, as it WILL make a difference when everyone is using the more efficient parts, which will likely last longer because they don't run at >60C. No, 3W isn't huge, but it's EASY, and with not a terrible performance loss, i think these "green" drives are great.
Saving a couple of watts on a hard drive may not seem like much, until you realize that the industry sells something like 500 million units each year. If you figure an average life expectancy of about 3 years for a hard drive, that would mean that there are probably over 2 billion hard drives currently in use. Now if each hard drive uses a few less watts, the overall electrical use can really be significant.
I really want to see a review on the reliability of these 1.5TB hard drives...seems to me they all have HORRIBLE ratings at newegg...something like 25%+/- 1 star ratings and 50%+/- 5 star ratings which is horrible considering that most other hard drives are somewhere around 75%+/- 5 star ratings and 10%+/- 1 star ratings.
The amount of energy taken for all of Tom's readers to DL this article greatly dwarfs the energy saved by using eco drives of low performance that save you around ten bucks over their life span and initially cost you a lot more than regular drives of the same performance.
perhaps it would be nice to see the power measurments on some notebook HD variants.Power requirement most of the time means only something in the server and notebook sector.The desktop sector can live perfectly fine with a HD that consumes 3Watts more than another one!
Yes, please do an update to include the Seagate LP drives; it's hardly worth doing an article for only 2 drives, don't'cha think?
Does anyone know where the Samsung drive can be purchased?
