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.

Wall Street Journal | Email this | Comments What's 2.5-inches wide, 7mm tall and silent as a whisper? Well, hopefully it's Hitachi's new CinemaStar hard drives. We know for certain that these platters of polarized bits will fit in your standard 2.5-inch drive bay, we'll just have to take the company at it's word (for now) on the silent bit. Three new families of disks just hit the market, the Z7K500, Z5K500 and budget-friendly C5K1000. The first two options are 7mm high, allowing them to slide nicely into small form factor PCs, DVRs and even laptops. Both top out at 500GB, but the Z7K ekes out better performance by whipping its platters around at 7,200 RPM, while the Z5Ks save energy and noise by ratcheting back to 5,400 RPM. The C5K comes in a slightly bulkier 9.5mm height, but this 5,400 RPM drive does reach the lofty storage size of 1TB. For now the drives are available in limited quantities to OEMs, but hopefully that will change soon enough. Check out the PR after the break for more details.
