A new hard drive technology based on lasers

After the perpendicular technology, there is another advancement in hard drives technology.

On a very interesting news, Ars Technica reported that researchers at Radboud University Nijmegen in the Netherlands were able to achieve a much faster perfoming drive using laser beams to transfer data on a magnetic hard drive at speeds of up to 40 femtoseconds per bit, i.e. about 100 times faster than currently available HDDs.

This new technology is able to increase the speed of data storage, but it has no potential to increase also drive capacity. Of course, this is only an experimental technology and there are some not yet solved issues, but it seems really promising.

Just so people realize how much 40 femtoseconds is... 100 femtoseconds is the time required to travel across a human hair, if traveling at the speed of light

A femtosecond is to a second what a second is to about 32 million years. Source: http://en.wikipedia.org/wiki/1_E-15_s

Wow that is SLOW!!! :-)

What use is this technology alike, if all we have is not the bottleneck in internal transfer rates of a HDD.

btw, just how many people know current HDD has already surpass 1GB/s mark internal transfer rate, while interface is still working at less than 40MB/s as in SATA2. And just how much is 40 femtosecoond compared with 4ms, with state of art average mechanical seek, I wonder
