SSD Breakthrough Sees Performance Hit 9.5GB Per Second

Following the news Seagate is preparing a 3TB HDD, the question was posed: how will SSDs follow that? The answer: emphatically.

Speed and power consumption are arguably an SSD's biggest assets and now researchers at the University of Tokyo working with Nikon have unveiled a breakthrough which sees them hit mind bending new levels.

Focusing on how SSDs write their information the team has come up with the 'Single-cell Self-boost method' which is rather complex, but in essence uses a new form of ferroelectric NAND (the building blocks of flash memory). This results in less power needing to be stored in NAND cells with the main voltages held in a 'floating gate' between them. The result is a reduction in SSD power consumption by a stonking 86 per cent (sub one volt) and the always-ready floating gate has led to incredible write speeds of up to 9.5 gigabytes per second!

The inevitable downside to all this is with the breakthrough just being announced not even the slightest hint of a date has been put on bringing the technology to retail devices. Then again planting one of these SSDs in one of today's computers would simply result in bottlenecks galore elsewhere so we're not missing too much in real terms as yet.

Still it's nice to know one part of the future is ready!
