Notes:	Costs are based on the cost of the drive and media to store 10GB and 100GB of information.
	Drive and media prices are based the average price for a bare drive and the indivdual price for a 3- or 5- pack of media.
	Drive and media prices were correct on 15th April, 2000
	Media capacity is based on the uncompressed size of the media involved. All media can potentially store compressed data, whether the compression is handled in hardware or software. Compression rates vary from 1 to 2x based on the data you are storing. The average compression ratio for the type of data stored on your machine is about 1.6x.
