The iPad comes in three capacities of 16GB, 32GB and 64GB. If that isn't enough for you while you are on the road then perhaps the HyperDrive HDD with a 750GB capacity could be for you.
The HyperDrive HDD is built by HyperMac and is capable of connecting up to the iPad via the camera connection kit. Once connected you have an extra 750GB of storage space for your media files.
Features included in the HyperDrive show that it has a built in memory card reader that can read 12 different formats of cards. A 3.2 inch display on the front let you see what is available on the external HDD.
Price wise, it costs $249 without the hard drive. If you add $50 to that taking it to $299, you get a 120GB model and take it up to $599 you get the 750GB hard drive.
