Lucas123 writes ""After 10 years of development, Western Digital announced today that it's shipping the industry's first helium-filled hard disk drives with 6TB of capacity, 50% more storage space than any other 3.5-inch drive out today. In addition to a 2TB capacity increase over today's 4TB drives, the new hermetically-sealed Ultrastar He6 hard drive uses 23% less power and are 38% lighter than predecessors. Because helium is one-seventh the density of air, the drive's disk platters and actuator arms benefit from reduced friction, allowing WD to cram seven disk platters into the same form factor that previously could only hold five platters. The hermetic seal also keeps contaminants out of the drive."
