E-Discovery Fact Week Day Four: Examining E-Discovery Data Volumes
July 26, 2018
Welcome to day four of E-Discovery Fact Week, our online celebration of the importance and value of e-discovery in the legal process, designed to bring awareness of e-discovery to the legal community at large. All week long, we've been tweeting, blogging, and sharing interesting facts about e-discovery for your education and entertainment. E-Discovery Fact Week is part of the larger E-Discovery Day celebration, which last year reached over 2,000 legal professionals at 13 live events and 15 webinars. Today, we'll be sharing facts the amount of data involved in e-discovery matters.
How Much Is a Gigabyte of Data?
A gigabyte can contain anywhere from 15,000 to almost 700,000 pages of data. In its white paper How Many Pages in a Gigabyte?, LexisNexis provides the following approximate figures (among others):
Image files: 15,000 pagesMicrosoft Word files: 65,000 pagesEmail files: 100,000 pagesText files: 678,000 pages
How Many Gigabytes Are in a "Typical" E-Discovery Matter?
As any e-discovery professional would agree, defining a "typical" matter is a difficult exercise. However, in a 2016 presentation on e-discovery and data analytics, Jay Brudz, Chair of Information Governance and eDiscovery at Drinker Biddle, suggested typical ranges of
10-15 custodians per matter5 - 20 GB per custodianSolidly within these ranges, 10 custodians at 10 GB per custodian gives us a nice round number of 100 GB--equivalent to 6.5 million pages of Microsoft Word documents. Using that as a sample typical matter, we can examine what that data volume might look like. The comparisons are illuminating.
What Does 100 GB of Microsoft Word Documents Equal?
At 5,000 pages per 10 ream case of paper, that “typical” matter contains 1300 cases of paper worth of data! Some real-world examples of what that looks like include:
A stack of paper over 2,150 feet tall, taller than every building in the world except the Burj KhalifaOver 4.2 million square feet of paper, enough to cover over 73 football fields65,000 pounds (more than 32 tons) of paper, more than 10 African forest elephants weighMore than 130 times the amount of data in your (or any individual's) DNA
