I'll agree with the others that your estimates are "conservative", but it also 
leaves out the many companies whose data is the heart of their business.  I've 
worked for a few in the past, and am working for one now.  Anacomp is a 
document repository and format translation company.  compete.com does 
statistical analysis on every single web page access through several national 
ISP's.  They have a 6TB SAN online, processed using a 48-node Beowulf cluster.

You're assuming that transactions are the only thing stored in that space. 
Online catalogs today take up a lot of space, because everything needs to be 
massively cross-categorized and indexed.  Normalization sometimes has to be 
compromised in the name of speed.  Views on multiple tables to speed access 
can double or triple the storage requirements.  Reviews of producs.  Reviews 
of sellers.  Web-based messaging.  The accounting systems that the 
transactions feed.
