Converting a number of large (~300GB or greater) source files to a much larger number of smaller target files requires a storage platform with capacity for high IOPS, as well as the capacity to perform many multiple concurrent read/write operations.When application vendors tout scale and performance numbers, be sure to look at the full environment for whatever testing the vendors have done.  Part of that environment will be the storage used.  Realize that you might not get the same performance if you are using existing storage that you have in your data center.   You should also consider your scale needs.  For example, if you are an organization that does ECA on a case-by-case basis and your matters average 20 GBs, a highly scalable solution is going to be overkill for now.  However, if you are a large organization taking a proactive approach to eDiscovery and building connectors to multiple data sources, you will want a good level of scalability for your eDiscovery applications.  It will make sense for you to take a hard look at the storage underlying these applications to make sure that they can be high-performance.
