IBM claims a solid state breakthrough -

A survey commissioned by IBM discovered that its enterprise customers are greedy for solid state disk drives rather than spinning hard drives, any more. It said developments in solid state storage promise economies in size and power.

IBM surveyed 250 IT professionals in the USA and over half of them said that their organisations needed a better strategy for storage.  

The enterprises also want better delivery and they want it at a lower cost oo. Forty three percent of those surveyed said they will either adopt solid state drive technology in the future or have already made the shift.

And of that 43 percent, three quarters said they wanted to speed up data serving within the enterprise. Cost is inhibiting those surveyed who said they aren't using SSD tech.

IBM Research believes it has the answer to these enterprise dreams by developing "racetrack" technology which uses electron spins to to access and move data using nanowires. IBM thinks that the technology will let manufacturers make devices that provide more information, maybe as much as 100 times more, and use less energy.

Right now, said IBM, an ordinary transaction driven data centre uses 1,250 racks of storage, occupying 13,996 square feet and gobbling up 16,343 kilowatts. But IBM has the notion that by 2020, storage class memory could allow all that data to sit in one rack, occupy 11 square feet and consume 5.8 kilowatts.

However, enterprises are still chary of cloud computing, the same survey found - only a third will switch to cloud storage in the future.
