Storing them vertically is a little like erecting a high-rise building, enabling engineers to pack more per inch into the total amount of disc real estate. Prior to this innovation, bits were stored on flat sections of the platter.

A relatively new breakthrough is technology that increases areal density by aligning bits of data vertically or perpendicularly, instead of horizontally. Still, consumers can expect to see significant improvements in capacity over the next few years. Butler expects drive capacity to continue to grow rapidly for the next couple of years but eventually slow down. The areal density of today's drives, according to Butler, is 64 million times higher than it was back in 1956: an increase of 46 percent per year. Storage capacity for drives is measured in areal density – the number of bits per square inch of storage surface. If these steps don’t work for you, contact the developer directly.The device, which stored five million characters (a bit short of 5 megabytes), cost $35,000 in 1956 dollars and stood 5 feet tall, a little less than 6 feet wide and 2.5 feet deep.
