Hard disk: back on the molecular storage

The hard drive is becoming 50,000 times more dense. Finally, it remains to the road before coming to industrialise the process...

We you talked about at the beginning of the year, IBM would have found a way to store a magnetic bit with only 12 atoms. Other researchers of the University of Karlsruhe, at Strasbourg and Tokyo would for their successful feat with a single molecule of 51 atoms. If researchers at these universities are not better than those of IBM, the feat is in the form of the maintenance of the State of the bit.

The Interior of a kind of shell maintained by these 50 atoms constituting the organic molecule, they placed a last atom of iron. Thus, by spin transition, the iron atom can be charged either positively or negatively to induce a change of State and therefore be read a posteriori as a bit to 0 or 1.

Molecular storage of KIT (Karlsruhe Institute of Technology)

Toshio Miyamachi, researcher at the Center for functional nanostructures of the Karlsruhe Institute of Technology (KIT) indicates that with its structure as nanomolecule, it is possible to store 50,000 times more information on an area equivalent to our current with a reliability hard drives since it is here to add or remove from the electrons in an atom of iron. To compare, if we take a disk trays of 1 sold To currently in the trade, we could then obtain almost 50 inches (or 50 million GB) with this technique.

If the technique seems simple, in practice it is more complicated because he must write the bit in each nanomolecule. With our technology of reading and writing at positioned magnetic head perpendicular to the plateau, he will have to find a way to reduce the finesse of this head to match the fineness of the molecule. A new field of research is therefore opened for its universities and which we will still hear talk about for years to come.

Dropbox: two times more storage for the same price

Dropbox feels visibly threatened the market online storage and synchronization "cloud" where these new efforts...

Dropbox (1).PNGThe online storage market is increasingly competitive and one of its players the most, Dropbox, has announced a significant decrease in the rates charged to its pay-TV offerings. Or rather, it doubles the storage capacity proposed for unchanged rates, which is not quite the same thing, since the amount levied on bank card by the service remain, it, unchanged.

Thus, to be more competitive Drive of Google services, Microsoft SkyDrive, Hubic of OVH, Cloud Drive of Amazon and others, Dropbox offers now not 50 but 100 GB for $ 9.99 per month and 200 GB for $ 19.99 per month. And synchronization specialist was also able to launch a new offer of 500 GB of online storage space, charged $ 49.99 per month.

Despite these efforts, Dropbox is more expensive than most of its competitors. The 100 GB being charged $ 4.99 a month in Google, and $ 4.16 per month at Microsoft. But with the principle of sponsorship of Dropbox (500 MB earned by recommendation), it is possible to significantly extend the limit of 2 GB for free available up to 18 GB. Good, of course, until there is little time, Microsoft offered on SkyDrive 25 GB to a Windows Live account holders...

Online storage: Lastly, the clients for Amazon Cloud Drive

Amazon strengthens its offer Cloud Drive from clients for Windows and Mac.

It is the war of the "cloud". Online storage is becoming a more and more competitive market and the recent launch of Google Drive did that accelerate the changes made by the players to their offers. Thus, Dropbox is more generous still in storage in sponsorships, Microsoft accepts on his SkyDrive files up to 2 GB and offers clients for all OS (desktop and mobile), Hubic builds on the unlimited price, etc.


There was only Amazon which had not taken the opportunity to improve the offer of its Cloud Drive. It is now because one learns that the digital locker to Amazon is more accessible via clients (finally) available for Windows and Mac (from Windows Vista and Mac OS X 10.6).


Amazon opens so very clearly his Drive Cloud storage of all types of files, and is not to be exceed the market where it is present since long. However, the offer remains fairly simplistic, and if small software in question facilitates the transfer of files from and to the Cloud Drive space, synchronization or collaborative work on stored documents are not in the program.


It's also a quite similar to most others, supply to see that 5 GB online storage space is available (the size of the music library is not counted). However, beyond this implementation free mouth, Go is charged $ 1 to the year. For $ 20 per year, the user has for example access to 20 GB of storage in the cloud, while Microsoft offers 25 GB with SkyDrive. And for 1 To, it will cost $ 1000 to the year... Is much more expensive than the $ 50 per month requested by Google Drive for the same storage space, and less interesting than the supply unlimited of Hubic (OVH) invoiced €84 per year.

Another large deficit, Amazon Cloud Drive does not propose to client for smartphones or tablets. In short, it still work Amazon to their place of choice in many online storage services. Probably starting with boost its free offer to attract users, before hope to sell them additional GB...
