Almost every talk I see starts with some statistics about the growth of data. Here Datanami updates some of this, with related quantifying of related aspects. Below I show just the first two, more at the link. Impressive and even useful at times to scale your usage. Ready?
10 Big Data Statistics That Will Blow Your Mind By Alex Woodie in Datanami
