"This revolutionary method allows the recording of Terabytes (thousands of Gigabytes) of information per second"
Therefore, If you can write 1TB/sec the seek it would pretty much outperform any SSD cluster, in terms of writespeed.
unfortunately, nothing is said about read speeds/access times and I assume that that will be a harder problem. Because they are still storing the data magnetically and the platters don't emit heat based on their polarisation, they still have to pretty much read like normal hdds do.
You cannot (until now, like it was not possible to alter the magnetic polarisation of metals other than with another magnetic field) sense the polarisation except for with another magnetic field.
I am really interested in how that will turn out, but before they make a significant advance in read speeds I doubt that the technology will make it into consumer grade HDD's any time soon.
It's a damned cool technology, and I hope it leads to something useful, but I just can't see it becoming the prevalent paradigm.
But mobile, in our case, means also a shift to the cloud, where significant more potent storage technologies could make a real difference.
I really hope, too, that technology will lead to something new.
