Western Digital Adds Helium To Its Hard Drives

Aside from making 6TB drives possible, I wonder if the Helium makes Western Digital's new hard drives give off a goofy high pitched whine now? big grin

All that drag from the air limits the number of disk platters that can be stacked inside a single drive. Right now, the standard calls for five platters inside a one-inch-high drive enclosure. Building a sealed drive that’s packed with helium eliminates that drag, and thus allowed for platters to be packed inside the enclosure more tightly. Where you once could fit only five platters, you can now fit seven. That means more storage capacity per drive. The first drive out of the chute has a capacity of six terabytes, versus four for conventional drives.
