Terabytes of data? I put together this answer based on what I read at that first url: Multiply expression levels of thousands of genes and mutants times numerous growth and disease states here is a good article It's sink or swim as a tidal wave of data approaches Nature 399, 517-520 (1999) Briefing petabyte=1,000 terabytes exabyte=1,000 petabyte All the words ever spoken by human beings amount to about five exabytes. nature.com Here is the next question--building molecular movies: Message 10507272 Here is the link to The Matrix biospace.com (...and now I am reminded what else is important when distinguishing these chips--speed) Nanogen: Gallahue notes that the company has developed a 10,000 electrode array as part of a partnership on drug discovery applications with Aventis Research and Technologies (an affiliate of Hoechst AG). But he believes the applications the company will pursue initially can be served by the chip now in beta tests. "What makes us different is speed and specificity, as well as the ability to create your own array," says Gallahue. All of these aspects are made possible by the electronic aspect of Nanogen's chip.

Affy's chip has been described as not suited to high throughput screening. I'm not familiar with Gene Logic's offering. Incyte reported that they have installed computers that are in the supercomputer range, for managing their genetic databases. Seems to indicate that the threshhold for entering this field will be quite high. The quote you posted regarding Nanogen is one more reason to spread your investment throughout these companies. Each of these platforms has different strengths and weaknesses, and it's way too early to be predicting the eventual winners. An early leader in personal computers was Commodore, with a true multi-tasking machine using icons and a GUI long before the Wintel machines. Zilog owned the CPU business. CPM was the DOS of choice. Betamax was earlier and better than VHS...
