What's faster than your PC? Your smartphone!

Samsung has announced at the end of February 2016 the beginning of mass production of 256GB chip for the smartphone market. These chips are twice as fast as the SSD storage you have in the PCs.  They can manage up to 45,000/40,000 input/output operations per second, whilst the current SSD manages 19,000/14,000 IOPS. 

The new chip has two internal bus supporting data transfer at 850MB/s and can write at a speed of 260MB/s, that is three times as fast as the best SD cards on the market today.

What can you do with such performances? You can play 4k video and actually you can even play two 4k clips in a split screen mode, leaving enough bandwidth to support multitasking, like searching images or downloading video. 256GB is enough to store almost 50 HD full length movies.

This is strengthening the trend towards mobile processing. New smartphones have a USB 3.0 port that can let you swap a 5GB HD movie with a friend smartphone in just 12 seconds.

This is interesting in view of the 5G, where communications will take place using a variety of channels, not just those provided by the Telcos. You can easily imagine that some data you may be interested in will already be available in other phones in the vicinity. New search algorithms will create a map of the distributed storage, dynamically changing, provided by a dense network of smartphones and you'll be able to access these data through a communication fabric consisting of the clouds of phones in proximity with one another.  This will clearly require a secure communication environment, and this will be part of the trusted/secure cloud at the edges (also called trusted fog). The good news is that this communications will be using very low power, given the proximity of the phones.

The 128GB chip was announced last year, so after 12 months we get double storage capacity plus faster speed. Moore's law, in the storage department, is still working!
