There are several published examples of native XML storage reducing storage costs. In the past, many people claimed that ever-decreasing storage costs marginalize the value of storage savings. However, these people were considering only the cost of the actual storage devices. When you start taking factors like physical location management and power consumption into account, reducing storage costs can quickly become a very important consideration.

The first example I’d like to quote comes from a major Wall Street firm. They achieved greater than 5x storage savings by moving to the native storage of XML data together with the use of the accompanying compression capabilities. In other words, after adopting IBM DB2 pureXML, their data required 20% of the storage space it previously required.

A major North American bank achieved a 3.9x storage savings thanks to native XML storage alone. When DB2 compression was used, it had a 6x storage savings impact. By combining the native XML storage with compression, that North American bank realized a head-turning total of 11x storage savings.

Finally, an example from the telecommunications world. A prominent Chinese telecommunications company achieved 4x storage savings thanks to native XML storage.

When applied to a large scale deployment, these storage savings can have a significant impact of the operational costs of such organizations.
