Healthcare devices generate a tremendous amount of data. Too much, in the minds of some doctors, who worry the flood of information generated not only by devices in healthcare settings but also by emerging "recreational" health monitors and in-home health tech, can lead to "data overload" that will cause providers to lose the forest for the trees and misdiagnose patients. Healthcare IT professionals also fret about the challenge of storing and analyzing this fire hose-volume stream of data. And for good reason. The so-called "internet of everything" – networked products which in the healthcare field run the gamut from pacemakers to MRI machines – is expected to generate a staggering 507.5 zettabytes (that's 507.5 trillion gigabytes) of data by 2019.
