Gone are the days when you have to sacrifice size for speed with an SSD drive in your laptop. At the Flash Memory Summit in California, Samsung just revealed a new 2.5-inch SSD drive with an incredible 16 terabytes of storage. It’s not only the world’s largest SSD—it’s actually now the world’s largest hard drive, period.

So how on Earth did Samsung pull off a such an incredible feat? Inside the PM1633a SSD you’ll find stacks and stacks of the company’s latest and greatest 256Gbit NAND flash dies, which are twice the capacity of the 128Gbit NAND flash dies currently in use. According to Ars Technica’s calculations, there should be somewhere around 480 to 500 of the dies inside Samsung’s new SSD. Which is even more impressive given it still fits inside a 2.5-inch housing, although it’s probably a lot taller than most.

The answer to the million dollar question about the new 16TB SSD—how much does it cost?—is thankfully not a million dollars. However, the first units will probably sell in the range of $5,000 to $7,000 and will be targeted for use in servers and other enterprise applications. But over time, as with all technology, the massive SSDs will certainly drop in price and trickle down to consumers—just in time for our storage demands spiking thanks to 4K movie downloads.

The Defense Advanced Research Projects Agency (DARPA) website reports that two of DARPA’s Young Faculty Award (YFA) recipients have developed nanoscale electronic switches with reprogrammable features, similar to those at play in inter-neuron communication in the brain, which could find uses in next-generation reconfigurable electronic devices and brain-inspired computing.

Intel and Micron Technology on Tuesday unveiled what they touted as a new kind of memory chip that could “revolutionize” computing devices, services and applications.

Intel and Micron have a new way to store data that they say is denser, tougher, and faster than the competition, and it’s already starting production. In a live keynote today, the companies announced 3D Xpoint, a new category of non-volatile memory that claims to be 1,000 times faster than the NAND architecture underlying most flash memory cards and solid state drives. The new architecture does without transistors entirely, relying on a bulk material property change to switch bits from a low-resistance to a high-resistance state. From there, memory cells are layered in an intricate three-dimensional checkerboard pattern that Intel researchers say is 10 times denser than conventional memory.

UT Dallas scientists have constructed novel fibers by wrapping sheets of tiny carbon nanotubes to form a sheath around a long rubber core. This illustration shows complex two-dimensional buckling, shown in yellow, of the carbon nanotube sheath/rubber-core fiber. The buckling results in a conductive fiber with super elasticity and novel electronic properties. (credit: UT Dallas Alan G. MacDiarmid Nanotech Institute)

An international research team based at The University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to more than 14 times their initial length and whose electrical conductivity increases 200-fold when stretched.

SSDs and other flash memory devices will soon get cheaper and larger thanks to big announcements from Toshiba and Intel. Both companies revealed new “3D NAND” memory chips that are stacked in layers to pack in more data, unlike single-plane chips currently used. Toshiba said that it’s created the world’s first 48-layer NAND, yielding a 16GB chip with boosted speeds and reliability. The Japanese company invented flash memory in the first place and has the smallest NAND cells in the world at 15nm. Toshiba is now giving manufacturers engineering samples, but products using the new chips won’t arrive for another year or so.

“An analysis of the history of technology shows that technological change is exponential, contrary to the common-sense “intuitive linear” view. So we won’t experience 100 years of progress in the 21st century — it will be more like 20,000 years of progress (at today’s rate). The “returns,” such as chip speed and cost-effectiveness, also increase exponentially. There’s even exponential growth in the rate of exponential growth. Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity — technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.” — Ray Kurzweil.
