Towards 10TB SSD

Samsung has been leading evolution of SSD memory (Solid State Drive) and managed to stack few layers of memory on the same chip thus increasing capacity. Now Toshiba has announced a leap in stacking by developing the world’s first 48 layer SSD with a single chip capacity of 128Gbit (each cell contains 2 bits) equivalent to 16GB.
The cells use 15nm technology and chips can be aggregated on gum-stick sized memory board with a capacity exceeding 2TB per board.
Toshiba has provided a few samples to its clients but industrial production won’t be available till middle 2016. The plant for manufacturing these 3D stacked SSD is under construction. 
Toshiba is not the only one working on multislacking layers of SSD. Intel and Micron have recently announced working on a 32 layer SSD (like Samsung) with a capacity per chip of up to 384Gbit (48GB) resulting in a gum-stick sized memory of 3.5TB or on a 2.5-inch board with a capacity of 10TB, overtaking present hard drive.
Also in this case production will only start next year and probably we should wait till 2017 to have the 10TB SSD at an affordable price and 2020 to reach the pricing point of hard drive. Anyhow, it is just a matter of few more year and we will get more capacity, faster memory and lower power consumption at a lower price! Not bad…

About Roberto Saracco

Roberto Saracco fell in love with technology and its implications long time ago. His background is in math and computer science. Until April 2017 he led the EIT Digital Italian Node and then was head of the Industrial Doctoral School of EIT Digital up to September 2018. Previously, up to December 2011 he was the Director of the Telecom Italia Future Centre in Venice, looking at the interplay of technology evolution, economics and society. At the turn of the century he led a World Bank-Infodev project to stimulate entrepreneurship in Latin America. He is a senior member of IEEE where he leads the Industry Advisory Board within the Future Directions Committee and co-chairs the Digital Reality Initiative. He teaches a Master course on Technology Forecasting and Market impact at the University of Trento. He has published over 100 papers in journals and magazines and 14 books.
