Hasta La Gadget!

HGST, a subsidiary of Western Digital, announced on Monday the launch of its first helium-filled hard drive. The new Ultrastar He6 drive comes with a 6TB capacity in a 3.5-inch drive enclosure.

According to HGST, having helium in the enclosure has significantly less friction than air, allowing for less energy needed to physically move platters around inside the drive resulting in more platters with an acceptable performance. More platters mean more drive space with a general increase by three quarters over a standard air-filled hard drive.

The challenge has been to create a chamber in the drive that was tight enough to avoid leaking the helium, and HGST assures us that it is a safe volume with “less helium than a balloon”. Pricing was not initially available, however the company stated that it will “…cost-effectively extend the capacity and cost-per-gigabyte curve for many product generations to come.”

We know, we know, Google has the whole hot air balloon thing covered. But this idea is a bit different. It consists of a group of “helikites,” or small load-bearing balloon-kite hybrids, which can quickly be launched to form a network of LTE or WLAN masts up to an altitude of 2.5 miles, providing data coverage following an earthquake or tsunami. A standalone rugged suitcase, or “Portable Land Rapid Deployment Unit,” contains everything needed for activation in tough conditions. Researchers behind the project, including German R&D firm TriaGnoSys, have even found a way to integrate the temporary network with existing cell towers that remain in tact on the ground — a feature that makes the system suitable not only for emergencies, but also for expanding mobile coverage during planned events in remote locations. Of course, the helikites would eventually drift apart and lose connectivity, probably after around four days depending on the wind, but these things never travel quite as far as you’d expect.

With certain exceptions, talk of advanced hard drive technology regularly has a tough time escaping research labs. Western Digital’s HGST is promising a much more tangible project that could boost data capacities by a wide margin. By filling the gaps between drive platters with less buffeting-prone helium instead of air, HGST can safely fit as many as seven platters in a typical, 3.5-inch desktop hard drive instead of the current five. Going with the lower density gas creates a raft of side benefits, such as fitting more data on a single platter along with reducing the drag that both slows down and heats up the disk. We’ll have to wait until 2013 to see shipping helium-filled drives in our PCs; given the slightly exotic nature of the technique, though, we wouldn’t count on HGST or Western Digital handing out drives for free like balloons at a birthday party.
