I4U reports of new Holographic Holographic Versatile Card (HVC) made by Optware that is only as big as a credit-card but stores 30GB of data. Nice. 30GB is about 6 times more than a DVD can store and in closer to the capacity of next generation DVD formats like Blu-ray or HD DVD. A HVC costs about 90 cents. A HVC drive is supposed to cost $1,800.
