Facebook is Fusion-io's biggest customer

While the company's unlikely to have sold many ioDrives to good old Joe Consumer, its upcoming IPO application features an impressive list of corporate clients, highlighted by Facebook, its biggest customer, IBM, HP, and Credit Suisse -- the latter using Fusion-io technology to speed up the mathematical alchemy of making money where there was none before. Taken together with strategic investments from Samsung and Dell, these deals paint a rosy outlook for the Woz-employing startup, however it's worth noting that profitability is still a decent way away.
