The A*STAR Data Storage Institute (DSI) released its thinnest 5mm hybrid hard drive in a 2.5in form factor. The 'A-Drive' offers up to 1TB hard disc drive with 32GB solid state drive, targeted specifically for tablets, ultrabooks and future data centres. One of the main challenges in reducing the thickness of current 7mm HDDs by almost 30 per cent without compromising on its performance and stability is its spindle motor design. To achieve a reduction in size, DSI researchers developed a proprietary axial field motor that runs smoother, quieter, more efficiently, lowering power consumption by up to 70 per cent yet at a fraction of the cost of SSDs.

DSI together with its sister research institute, SIMTech is developing a helium-sealed ceramic enclosure for the slim hard disc drive. As compared with air-filled drives, helium-filled drives are likely to achieve 50 per cent reduction in positioning error caused by flow-induced vibrations, reduce other mechanical resonances in the drive, decrease power consumption by 30 to 40 per cent, increase the corrosion resistance of the head and media and provide a smoother temperature distribution in the drive. The helium-sealed ceramic enclosure will push the development of an external wireless storage application for A-Drive that would include embedding Wi-Fi communication and wireless inductive charging function.
