Hello @JeffLobb,
I don't believe that there's a metric per se to gauge the difference between collecting from 90TBs or smaller files. With any type of collection, it's just going take more time to run against 90TB of data. The question can be answered better though the use of targeted collections in your eDiscovery workflow.
With EV Collections in Clearwell you have a number of options, e.g. keywords, date range, traits, custodians, etc. to help you create targeted collections. The available options allow you to create precise queries against even large EV archives which in the end can produce highly effective results. Even before you actually collect any data, you have the option to run EV Searches which allow you to perform a mock run of an EV Collection. This enables you to have a preview, e.g. similar to EV search in EV, and an analysis of what would be collected. EV Searches allow you to modify the options until you get the results you want and before you collect any data. In addition, EV Data Holds are included which allow you to place a legal hold on any responsive data in EV.
I work with our Veritas business critical customers on a daily basis on leveraging EV Collections in Clearwell and can say that even against larger (and small, too) EV archives, EV Collections has been very successful.
