There has always been a high demand for faster hard drive. Although we’ve been getting RAM with high capacity. But due to the increased complexity of our software applications, no matter how much RAM that you have on your computers, you’d still be hearing the kind of annoying hard disk data swapping noise – the pretty long moment that almost all your application windows freeze.
Thanks to researchers at Radboud University Nijmegen in the Netherlands, who have found pretty promising technology to give us very high speed hard drive. And it’ll be 100 times faster than the existing that we can get in the market currently. To achieve 100 times faster, what it uses is laser light to write data to magnetic hard drive at very high speed. Instead of the conventional technology that uses magnets to write and read data. The technique works because photons transmitted by laser carry angular momentum, so they can interact with the hard drive. When each laser pulse heats a tiny space on the disk, so it will change its polarity – thereby storing a bit of data a little easier. Reversing the polarity of the laser pulses can produce equivalent of a 0 or a 1 of binary code on the disk storage medium.

hi there wow when will they come with computers or gaming consoles i am a hard core gamer i want 4 laser hard drives in a raid quad laser hard drives at 160 tb/s or 160 terabytes per second thats 640 terabytes per second 8 laser hard drives be 1.28 petabytes per second
