Comparing these two solutions side by side for 1 petabyte of usable storage, dispersal requires 40% of the raw storage of RAID 6 and replication. This translates to 40% less hardware, floor space, power and cooling. Factor in less time of a storage administrator as well, and it is easy to see how much more cost-effective dispersal is for large-scale systems.
Face it -- many executives fear the resume-generating event of having to admit the system they are responsible for has failed and is expensive and impossibly difficult to migrate to a more efficient storage solution.
Some executives may be in denial though -- "My storage is only 40 terabytes, and I have it under control, thank you."
Consider a storage system growing at the average rate of 10 times in five years per IDC's estimation. A system of 40TB today will be 400TB in five years, and 4 petabytes within just 10 years. This illustrates that a system that in the terabyte range that is currently using RAID will most likely start to fail within the executive's tenure.
Forward-thinking executives will make a strategic shift to dispersal to realize greater data protection as well as substantial cost savings for digital content storage.
