I worked for a university that spent about a million dollars on data storage for a research project. They estimated that they required about a petabyte of storage, so a big expensive storage array was purchased. In the end the project used just a few terabytes of storage because they miscalculated their requirements. It was a bit of a running joke that they spent a million dollars, when a $150 SSD would have been fine. They ended up repurposing the storage array (which is when I got involved). Luckily everyone has now moved to cloud, and life is better.
