Submission + - Flash Memory Slashes Power Use At Data Centers (discovery.com)

RedEaredSlider writes: Researchers from Princeton's School of Engineering and Applied Science have written a program called SSDAlloc, which tells a computer running to pretend that it's running using RAM, even though it's actually accessing the storage (flash) memory.

Most computers are designed to look in the RAM first for the data they need. Only after that does the operating look elsewhere, such as on the hard drive or a flash drive. That kind of hierarchical searching around can really slow things down.

SSDAlloc changes that, basically making a computer pretend the flash is the RAM. That cuts power consumption by up to 90 percent, the researchers say, because flash doesn't need power to run nor does it use the power that hard drives do.
