Western Digital's "Green" Hard Drives
MojoKid writes "Eco-friendly or 'green' products are becoming much more fashionable these
days, especially in things like high-end electronics, where the impact on the
environment and the disposal of these products is being regulated now by such
things as the RoHS compliance standard. In addition, power consumption is also
being looked at more closely for all the obvious reasons. Hard Drive
manufacturer Western Digital recently took the initiative by being the first
drive manufacture to produce and market
a lower power version of their Caviar line of hard drives. The
numbers here show that a green hard drive will probably only save an average
end user about 10 watts in total system power consumption. However, from a
data center perspective, where demand for storage is growing by the petabyte at
an alarming rate, 10 watts per drive can certainly add up quickly."
And I can confirm that. We used six of them in a home NAS server based on that review. Six drives in an Antec P182 case and you can't even hear the thing when it turns on.
It was so quiet we took it to an empty office because we couldn't believe what we were hearing, and that's when we found the ticking of my watch is far louder than the noise this computer makes when booting. Awesome drives, and an awesome case. Would highly recommend them both.
It's also important to point out that just because it only saves a single user 10 watts, that doesn't mean it's not a worthwhile endeavor. The post text suggests that this could add up for datacenters, but datacenters are nothing compared to the number of home computers our there, just imagine the impact on our global electricity infrastructure if every single computer's power consumption dropped by 10 watts. That's huge! Then think about the impact that would have on the environment (ie using less non-renewable resources). I think it would surely be noticed.
So yeah it's unrealistic to believe that every person is going to swap out their drives to use these, but when thinking about environmental issues it's important to put yourself in that frame of mind. I try do what I wish everyone would do. If everyone thought that way we'd get there eventually.
That being said I'm not going to swap out all my drives for these babies, but next time I need to buy or replace a drive, yeah for sure I'll cough up a little extra cash. As long as it's not just a marketing gimmick, and the price increase isn't too much, I'd be willing to take a slight loss on the principal alone. It's not just our pocket books that needs protecting.
But, as someone pointed out already, these drives are only a few bucks more than their non-green counterparts, so not only will they eventually save some cash, but they have the ability to make a difference too.
As a final thought, another thing that's important is make a point with manufacturers (through your wallet) that environmental issues matter. The more we think about it, and the more we get in the habit of making the small choices that all add up to a larger statement, the better off we all are.
