Hitachi Releases World's Most Energy-Efficient HDD
An anonymous reader writes "Today Hitachi released what they are calling the 'world's most energy efficient desktop hard drive' capable of reducing the active and idle power consumption by up to 40 percent over the previous generation." The drive will come in a range of flavors starting at 250GB and ranging to 500GB. Hitachi is promising these drives in high volume later this year.
You can bet these will be more pricey.
That doesn't really strike me as the first application of these drives. For something like a laptop, I could see it being very useful, where power usage is extremely important, and you don't mind waiting for the disk to spin up. In a datacentre, you most likely aren't going to be running the drive under conditions where it would have time to slow down, or you wouldn't be willing to make the sacrifice in speed that slowing down the drive would bring.

If its being used in a data center, what is the likelyhood that it will be able to "low-idle" for any length of time?
What percentage of Google's data do you think is actually being accessed at any given time? I'll bet most of the queries are for a small percentage of the data, plus most accesses are to the indexes and not to the actual data caches.
Maybe you are new here. The question is a classic one, and the meaning should be well understood by most readers. It is less clear but far more relevant to this group than the more wordy "but will Linux or XP be able to use this drive". And I explained the issue in the text body. Can you ever forgive me for the confusion that I have caused you?
I'm an American. I love this country and the freedoms that we used to have.
The parent is at least a tiny bit funny and insightful, but flamebait? Lot's of stress around, I see... Maybe because it is monday.
My laptop uses on 20 watts while operating, so cutting out 6 watts would be quite beneficial.

Perhaps in prebuilt systems and database servers, but it's more common than you'd think to just slap a bunch of SATA drivevs in raid 10 or raid 5 with a decent 3ware card managing the array. A decent sized(say, 300gb, because that's what's on newegg right now) 15k RPM SCSI drive from seagate will cost you $700. Why spend $1400 on 300gb of storage(you do need rendundancy if you need a 15k RPM drive), when you can spend the same money on a larger, faster array?
