On average, each gigabyte of data represents approximately $18,000.00 in e-discovery costs.
On a per-gigabyte basis, costs ranged from $125 to $6,700 for the collection of data, from $600 to $6,000 for processing electronic data, and from $1,800 to $210,000 for the legal review.
It is unrealistic to expect much room for improvement in the rates of human review. While it only costs about $.20 a day to buy one gigabyte of storage, it costs much more to have the stored data reviewed in the event of litigation. Thus, taking steps to establish a process and procedure for retaining only necessary data and deleting unnecessary data will reduce costs by reducing each gigabyte of data that needs to be reviewed.
