In its inaugural Global StorageSphere forecast, International Data Corporation (IDC) estimates that the installed base of storage capacity worldwide will more than double over the 2018-2023 forecast period, growing to 11.7 zettabytes (ZB) in 2023.
IDC's Global StorageSphere measures the size of the worldwide installed base of storage capacity across six types of storage media, and how much of the storage capacity is utilised or available each year.
IDC says the installed base of storage capacity is forecast by the following segments: storage media type, system applications (e.g., PCs, mobile phones, servers, etc.), region, consumer/enterprise, and cloud/non-cloud.
The installed base of storage capacity is a cumulative metric: It is equivalent to the amount of new storage capacity deployed over the span of several years minus the systems or storage devices that either fail or are retired or decommissioned each year.
The Global StorageSphere is a product of IDC's Global DataSphere program, which measures how much new data is created and/or replicated each year.
"The Global StorageSphere is large and diverse, encompassing many different storage technologies, and growing rapidly," says IDC research vice president John Rydning.
"Within the Global StorageSphere, enterprises, especially cloud providers, are increasingly being relied upon to store and manage the world's repository of data."
