'Disk drives weren't meant to be powered down and up and down' I'm told. But the PC industry has over fifteen years of experience in power saving technology approaches like spinning down/up drives in laptops. It's good to see a leading storage company step up and stand behind such an approach. As we all know, the #1 power culprit for big storage is disk devices-- it's 60% of the problem: http://www.wikibon.org/Image:TechnologyPowerUsageStorage2006.jpg Jacking device capacities and creating a power consumed per GB metric is illusory and doesn't address the problem directly. This does, especially in backup and archiving applications. Nice!
