Crystals hold super computer key
The crystals could be used as storage devices for desktop computers capable of holding 100-times more data than current systems. Scientists at the University of Edinburgh have been using low-energy lasers to make salt crystals in gel.
It allows users to store a terabyte of data in a space the size of a sugar cube within a decade. This would be enough to hold the equivalent of 250,000 photographs or a million books.
Dr. Andy Alexander, of the university’s school of chemistry, who developed the technique, said it could be used to improve on traditional methods of optical data storage, such as CDs.
Compared with the flat two-dimensional surface of a CD, three-dimensional optical data storage uses many more layers, in which tiny crystals could act as storage points. Also Information would be recorded in a similar way as on CDs – by making marks in a pattern, which are read using light.
On the 9th of January this year, a OCZ technology group from the international consumer electronics show (CES) 2012 had continues to push the performance and capacity envelope for cloud optimized solid-state storage. Yesterday the OCZ had announces a new storage device at CES 2012 which can hold up to 16TB!
Should you store treasured data on disks?
French National Centre for Scientific Research has found out after testing the longevity of the portable media. “There are surprised that the lifetime of discs are last longer than usually in the other discs but it’s also depends on some of the discs some of it are designed to last for centuries, some of it are rarely lasted longer than 5 to 10 years”, said physicist Franck Laloe. Every two or three years, you should copy your archive onto the fresh discs and you should re-copy them after five to six years times.
I have watch the new 4G signal that just arrived in England.
The 4G now coming in USB drive so you can connect to the internet, 4G is faster than WI-FI it 3time faster than 3G and it just take 1 minute to upload all one movie.
So now they try to spreading 4G all over Britain and the speed of 4G is 2.6 GHz.
The Sony XQD memory card has been announced, which will bring super speedy performance to photo enthusiasts also professional photographers for all kinds of image capture. Another improvement for Sony XQ is a memory card which is goes up to 32 GB
This timely announcement of the Sony XQD cards sits alongside the launch of the Nikon D4 today, an absolute beast of a DSLR and the first camera to include support for the XQD format.
A Finnish computer programmer who lost one of his fingers in a motorcycle accident has made himself a prosthetic replacement with a USB drive attached.
Jerry Jalava uses the 2GB memory stick, accessed by peeling back the “nail”, to store photos, movies and programmes.
The finger is not permanently attached to his hand, so it can be easily left plugged into a computer when in use.
Mr Jalava says he is already thinking about upgrading the finger to include more storage and wireless technology.
“I’m planning to use another prosthetic as a shell for the next version, which will have removable fingertip and RFID tag,” he wrote on his blog, ProtoBlogr.net.
Half of Mr Jalava’s left ring finger had to be amputated last summer after he crashed into a deer while riding his motorbike near Helsinki.
He says he was inspired to create the unique storage device when doctors treating him joked that he should have a USB “finger drive” after finding out that he was a software developer.
Summary of “global data storage calculated at 295 exabytes”
The calculation of the amount of data that has been stored by peoples from all over the world by 2007 is 295 Exabyte which is equal to 1.2 billion average hard drives. This was calculated by estimating the amount of data held on 60 technologies. Computer storage traditionally measured in kilobytes, then megabytes, and now usually gigabytes, then terabytes, petabytes, and then exabytes. (One exabyte is a billion gigabytes.)
The survey covers a period known as the “information revolution” the human society changes through time. It shows that in 2000, 75% of stored information was in an analogue format and people in the developed world could communicate eight times more information than people in the developing world, but that by 2007, 94% of it was digital and the gap between developed world and developing world has nearly doubled, and people in richer countries have 15 times more information carrying capacity.
The fastest growing area of information control has been calculated. During the past two decades the survey shows that the global computing capacity increased by 58% per year.
On the 9th of January, the CES (international consumer electronics show) which the OCZ ad present the new storage device that could hold up for 16 terabytes!!!
i had watch BBC Click about “How computers help artists at Sweden’s ice hotel”
they used a computer edit design sofware by loading the design the computer will automatically make a piece of art but it can make it up to the certain size so people still be needed to built an ice hotel. Still it help them to built because they can see how it look in 3D. high tech also help to control the light behind the scene.
