Apple just took the wraps off of its new 3TB Time Capsule automatic wireless backup hard drive. The company said that it will continue to offer a 2TB version of its Time Capsule alongside the new 3TB version, and it doesn’t look like there are any other differentiating specs. Apple appears to have also quietly updated its Airport Extreme product with support for up to 450Mbps file transfers over both 2.4GHz and 5GHz frequency bands, and the website has also been refreshed a bit. The 2TB Time Capsule drive is now available for $299 and the new 3TB model will set you back $499.
