Apple's NC Data Center To Double In Size?

But is a 500,000 square foot data center really enough for Apple? The company just announced last week that they would be expanding their app store to the Mac desktop and notebook platform, OS X. At first, Snow Leopard users will get a peek, with the full rollout expecting to take the computing world by storm next summer with the release of OS X 10.7 "Lion." Apple's app stores are growing at a rapid rate, and it's probably easier to build big now than to expand later.

Now, reports are suggesting that Apple may be considering "doubling the size" of the server farm, and it's also reported that T5 Partners is planning a shell building to house more servers on the existing property. Apple, nor any of the companies involved in the original data center construction, have confirmed the reports, but a local flyer has flown above the center and produced a YouTube video that helps to somewhat confirm that more work is ongoing. Have a look at the massive data center below. Is this just preparing for the Mac App Store? Or is there something even bigger planned?
