IDC has released a report on the ever-growing datasphere, what it calls the collective world\u2019s data, and just like the recent Cisco study, the numbers are staggering. IDC predicts that the collective sum of the world\u2019s data will grow from 33 zettabytes this year to a 175ZB by 2025, for a compounded annual growth rate of 61 percent.\nThe 175ZB figure represents a 9 percent increase over last year\u2019s prediction of data growth by 2025. IDC's \u201cData Age 2025\u201d whitepaper, sponsored by Seagate, says the datasphere has three locations. First is the core, which includes traditional and cloud data centers, second is the edge, which includes things like cell towers and branch offices, and third is endpoints, which include PCs, smartphones, and Internet of Things (IoT) devices.\n\nIt\u2019s really hard to imagine 175ZB of data, but David Reinsel, senior vice president at IDC, explains it in a video accompanying the announcement, which is hosted by Seagate. A zettabyte is a trillion gigabytes. Now multiply that 175 times.\n\u201cIf one were able to store 175ZB onto BluRay discs, then you\u2019d have a stack of discs that can get you to the moon 23 times,\u201d Reinsel says in the video. \u201cEven if you could download 175ZB on today\u2019s largest hard drive, it would take 12.5 billion drives. And as an industry, we ship a fraction of that today.\u201d\nNo doubt Seagate was happy to hear that.\nData and storage predictions for the year 2025\nThere are other remarkable stats for the year 2025:\n\nThe storage industry will ship 42ZB of capacity over the next seven years.\n90ZB of data will be created on IoT devices by 2025.\nBy 2025, 49 percent of data will be stored in public cloud environments.\nNearly 30 percent of the data generated will be consumed in real-time by 2025.\n\nThe explosion in cloud-based data will be matched by an increase in data stored in the core, or data centers. IDC says businesses are looking to centralize data management and delivery, as well as to leverage data to control their businesses and the user experience.\n\u201cThe responsibility to maintain and manage all this consumer and business data supports the growth in cloud provider data centers. As a result, the enterprise\u2019s role as a data steward continues to grow, and consumers are not just allowing this, but expecting it. Beginning in 2019, more data will be stored in the enterprise core than in all the world's existing endpoints,\u201d says the white paper.\nIDC sees a mix of old and new technologies, with traditional spinning hard-disk drives and solid-state drives both growing quickly and NVM-NAND technology taking off as the price comes down. Tape drives will grow, not die off, because they offer economical storage and superb archival functions.\nMore data will be stored in the core\nIDC also predicts by 2024, the amount of data stored in the core will be more than double the amount stored in the endpoint, \u201ccompletely reversing the dynamic from 2015\u201d as the core becomes the repository of choice. This is an interesting trend, since smartphones have greatly increased their storage capacity in recent years, with high-end smartphones now offering 256GB of storage.\nThe edge will continue to grow, driven by IoT and the shift to \u201creal-time\u201d data instead of data that is stored and acted upon later. IDC predicts the average person will have nearly 5,000 digital interactions per day by 2025, up from the 700 to 800 or so that people average today.
