Sony UK has launched the XQD S Series memory cards, which are said to outpace Compact Flas...

Despite numerous other format developments, Compact Flash has remained the memory card of choice for many of today's photography professionals. It's reliable, rugged and a good size for quick swap overs during shoots. CF is also a good deal faster than other media trying to break into the pro market. The addition of UltraDMA Mode 7 in Revision 6.0 took the format's maximum read/write speed up to 167 MBps but Sony has now managed to nudge ahead with the launch of its faster XQD S Series memory cards.  Read More

By using twisted beams of light, researchers have achieved data transmission speeds of up ...

Thankfully, data transmission speeds have come a long way since the days of dial-up when users would have plenty of time to twiddle their thumbs as they waited for an image or MP3 to make its way to their hard drive. These days, broadband cable currently supports speeds of around 30 megabits per second, which is a hell of an improvement. Now researchers have outdone that by a factor of around 85,000 by using twisted beams of light to transmit data at up to 2.56 terabits per second.  Read More

When completed in 2024, the Square Kilometre Array (SKA) will be the largest, most sensitive radio telescope ever created. It will consist of 3,000 individual ground-based dish antennas, linked to act as one big telescope – an arrangement known as an interferometer. While their combined total surface area will be about one square kilometer (0.39 sq mile), they will be spread out across a geographical area approximately 3,000 kilometers (1,864 miles) in width. They will be gathering about one exabyte of astronomical data per day, which is twice the amount of data that is handled by the World Wide Web on a daily basis. Today, IBM announced that it has partnered with ASTRON (the Netherlands Institute for Radio Astronomy), in an effort to develop computer systems that will be able read, analyze and store all of that data, and do so in an energy-efficient manner.  Read More

IBM's prototype 5.2 x 5 .8 mm Holey Optochip

Last Thursday at the Optical Fiber Communication Conference in Los Angeles, a team from IBM presented research on their wonderfully-named “Holey Optochip.” The prototype chipset is the first parallel optical transceiver that is able to transfer one trillion bits (or one terabit) of information per second. To put that in perspective, IBM states that 500 high-def movies could be downloaded in one second at that speed, while the entire U.S. Library of Congress web archive could be downloaded in an hour. Stated another way, the Optochip is eight times faster than any other parallel optical components currently available, with a speed that’s equivalent to the bandwidth consumed by 100,000 users, if they were using regular 10 Mb/s high-speed internet.  Read More

When you want to isolate communications between two devices or locations, a fiber optic link is one of the best ways to go. Under some circumstances, however, you might also want to isolate the transmission of power – in situations where traditional copper wire might prove unsafe or impractical, for instance. That’s why researchers at Sandia National Laboratories are developing a power-over-fiber (PoF) communications cable. It carries not only data, but also optical power.  Read More

The Wormhole Station can easily transfer files and share peripherals between Mac, PC, Andr...

The PC and Mac advocates have been debating for years over which is superior, with good arguments on both sides; but a third, often overlooked camp exists: people who use both. If you're in that group, then you know how frustrating it can be to have the perks of both machines, but the downside of few easy options for sharing files or peripherals between the two. That's why tech manufacturer j5create has rolled out the Wormhole Switch and the Wormhole Station, which allow file transfers between PC, Mac, Android, and iOS, as well as keyboard and mouse sharing.  Read More

An international team of researchers has set a world record two-way data rate over long di...

An international team is claiming a data transfer record that puts any home broadband connection to shame. At last month’s SuperComputing 2011 (SC11) conference in Seattle, researchers reached transfer rates of 98 gigabits per second (Gbps) between the University of Victoria Computing Centre located in Victoria, British Columbia, and the Washington State Convention Center in Seattle. Coupled with a simultaneous data rate of 88 Gbps in the opposite direction the team reached a two-way data rate of 186 Gbps to break their own previous peak-rate record of 119 Gbps set in 2009.  Read More

Internet service providers were recently exposed for grossly exaggerating the cost of prov...

A recent study shows that ISPs – which long maintained that data was their biggest expense – are grossly overcharging for data. The price increases to our mobile or land-based internet appear to be based on greed, not need.  Read More

Professor Jurg Leuthold led an experiment that achieved a data transmission rate of 26 ter...

With video content consuming ever more bandwidth, the need for faster data transmission rates has never been greater. Now a team of scientists at Germany's Karlsruhe Institute of Technology (KIT) are claiming a world record in data transmission with the successful encoding of data at a rate of 26 terabits per second on a single laser beam and transmitting it over a distance of 50 km (31 miles). The scientists claim this is the largest data volume ever transported on a laser beam and enables the transmission of 700 DVD's worth of content in just one second.  Read More

Using two interlocking flash drive-like USB sticks, iTwin allows two remote computers to a...

A lot of us have one "mothership" desktop computer, along with a laptop or notebook that we take on the road. Many of us also use one computer at work, and another at home. Inevitably, there are occasions where we're using one computer, but wishing we could access a file on the other. While there is remote access software that allows you to do so, the iTwin system offers what seems to be a much simpler solution – two flash drive-like sticks that plug into either computer, and let them communicate for free over a secure internet connection.  Read More
