Considering that one terabyte is generally estimated to contain 75 million pages, a one-terabyte case could amount to 18,750,000 documents, assuming an average of four pages per document. Further assuming that a lawyer or paralegal can review 50 documents per hour (a very fast review rate), it would take 375,000 hours to complete the review. In other words, it would take more than 185 reviewers working 2,000 hours each per year to complete the review within a year. Assuming each reviewer is paid $50 per hour (a bargain), the cost could be more than $18,750,000.”
