[NS] Heated hard drives could be super-quick

Physicists have discovered a new way to record data that could make future hard drives hundreds of times faster than existing technology - all you need is a little heat.

Hard drives store data using magnetic recording, with tiny sections of the disc magnetised in a particular direction to represent the 0 or 1 of a bit. Recording data involves flipping the direction, which is currently done using an external magnetic field. Now, a team of researchers led by Thomas Ostler at the University of York, UK have discovered that a short burst of heat can do the job much faster.

It was previously thought that heat could only assist in remagnetisation when used in conjunction with a magnetic field. It turns out that zapping a magnet with a laser for less than one trillionth of a second, momentarily raising the temperature by over 800 degrees Celsius, can have the same effect. The results were published today in the journal Nature Communications.

If only I had a hard drive and an oven.... WAIT... I DO!!

How much would I (a gamer) pay for a Hard Drive that writes faster? About the same as one that doesn't, would it even be able to keep with writing speed if two adjacent pieces are written on?

But what if I saved energy on the writing? How much would I lose in the spinning?

Exciting news to hear. Sounds like HDD's have found a way to possibly remain competitive against SSD's down the road.

SSD's just need to drop to a reasonable gb/$ ratio, it's not too bad now, but it's still more of a luxury than anything else.

SSD are still way to go for mobility, speed and power consumptions. Of course nothing will last long more than 10 years anyways. By then you'll have something new.

Yeah, but it is going to take a decade or so for this to come to market.

HDD companies have been working on heat-assisted magnetic recording (HAMR) and bit-patterned media for 4+ years. We still do not see any on the market.

SSDs are not a luxury for compiling, databases, or servers
