An interesting week for green data storage. University of Tokyo researchers have given us a tantalizing peek at our crazy-fast computing future with a new NAND flash writing method that can hit 9.5GBps and lowers energy requirements by 86 percent. Also this week, there have been rumblings that Seagate and Toshiba are prepping SSD-HDD hybrids. If this method of combining the performance and energy-saving benefits of SSD and the capaciousness of hard drives sounds familiar, it should. Samsung worked on similar tech a couple of years ago as a way to help speed up Windows Vista. Let’s hope Seagate and Toshiba can make it a reality for the Windows 7 crowd.
