The Big Data market is, well, big. But how large is the market really?

Experts look at the growth of the data market over time, forecasting everything from annual market revenues to the amount of data that will be created in years to come. There’s no going back and the market as we know it will only get bigger.

Here are 10 numbers that put into perspective just how promising, and potentially challenging, the market will become:

The number of times companies are more likely to identify security incidents within hours or minutes if they are heavy users of Big Data cybersecurity analytics, according to a Ponemon Institute report sponsored by Cloudera.

The increase of energy consumption in data centers between 2010 to 2014, far smaller than the 90% increase seen from 2000 to 2005. While data center energy consumption is not directly related to Big Data, it is an important stat to highlight that behind large-scale data sets and cloud computing is physical hardware that too needs modernization.

The upper end of the projected  salaries for Big Data engineers in 2017. Robert Half technology projected salaries would increase 5.8% this year over 2016 numbers to between $135,000 and $196,000.

The number of data scientists the U.S. will be short within a decade due to the rise of Big Data in the economy and across businesses, according to McKinsey.

The amount Forrester projects firms will spend on Hadoop and Hadoop-related services in 2021. The programming framework allows companies to process and store huge data sets in the cloud and an ecosystem of third-parties is working to help customers’ capitalize on it.

The number of smart devices projected to be connected by 2020, according to McKinsey. Combined with the billions of smart sensors, there is going to be an endless supply of data created from connected devices.

The projected revenue for the Big Data and analytics market in 2020, according to IDC. Commercial purchases of hardware, software and services will be driven in large part from financial services investments, including the banking, insurance and securities and investment services sector.

The estimated amount of data created every day, equivalent to 2.3 trillion gigabytes. That poses a long-term storage challenge to companies across sectors.

The amount of global data center IP traffic annually by the end of 2020, up from 4.7 zettabytes in 2015, according to Cisco. That translates to 1.3 zettabytes per month in data center IP traffic.

The amount of data that is projected to be created and copied annually, up from 4.4 zettabytes in 2013, according to an widely-referenced 2014 EMC report with research and analysis from IDC. Oh, and 44 zettabytes is the equivalent of 44 trillion gigabytes. If the amount of data was represented by stacks of 128 GB tablets, there would be enough stacks to reach the moon from earth 6.6 times, according to the report.
