5TB Hard Disks Next As Samsung Demos 1TB Platter At CeBIT 2011

A few meters away from the transparent, solar powered touchscreen 46-inch monitor that Samsung Electronics was displaying at CeBIT 2011 in Hanover, there was another disruptive technology on show, a new hard disk drive, the HN-D201RAE, a 2TB model with two 1TB platters.

This exceeds, by far the 750GB platters that are found in rival hard disk drives and power 2TB and 3TB hard disk drives. Samsung is therefore the first manufacturer to offer a platter with the required density of 636Gb per inch necessary to cram 1TB on a platter that goes in a 3.5-inch HDD.

In December 2010, HGST, which has just been acquired by Western Digital, introduced a 2.5-inch hard disk drive with a 500GB platter, the Travelstar Z-series.

HGST was the favourite until now to launch the first device to launch a 1TB platter, one which would have used the company's proprietary sixth generation perpendicular magnetic recording (PMR) technology.

Most hard disk drives have managed to cram four platters in a 3.5-inch hard disk drive but HGST introduced a five-platter monster back in 2007, the Desktstar 7K1000, which allowed HGST to be the first with a 1TB storage device on the market.

This means that Samsung may well introduce a similar model this year to reach the 5TB barrier (although a 4-platter, 4TB model is more likely). It might run hot but it will provide more than enough throughput thanks to SATA 6Gbps interface and ample cache (64MB or more) to justify the move.

As for the HN-D201RAE, it is part of the Spinpoint EcoGreen F6 family and comes with a 3-year wearranty, Advanced Format Technology, NoiseGuard, Ecoseek, EcoTriangle a new system on chip and Samsung's HD1 sensor.

Samsung has yet to tell when when it will go on sale and whether they have plans to release a 4TB hard disk drive in the first half of the year. 3TB hard disk drives are still commanding a premium in the market with the sweet spot being 2TB models which can be had for less than £70.

For now, why not have a quick peek at the hard disk drive below.
