That's just the beginning - if you've ever been in a ediscovery process, having large amounts of historical data is actually a liability - if instead of 100GB you have 10TB, you'll need to hand that over, and before that, to cull it so you don't inadvertently hand the opposition a huge lever to be used against you. Processing and reviewing 10-100x the data can take inordinate amounts of time more than you expect.
