![]() There is a concern that Moore’s law for integrated circuits will soon run out of steam due to fundamental physical limits on the size of the elements that constitute the circuit chip. This growth is driven not only by gradual improvements in technology, but also by periodic introduction of new technologies – in materials, designs, and processes.įig 1: Areal Density Chart from Tom’s Hardware Storage Review In fact, the storage density – time curve appears to have accelerated in last two decades. As you can see, Moore’s law (exponential rise in IC density) appears to apply to magnetic medium data storage densities as well. Hard Disks, since the first commercial release in 1956 by IBM, have undergone relentless evolution, as shown by the chart below. But will the same pace continue? Or is the venerable ‘Winchester’ ready for retirement? This article explores these questions. ![]() ![]() Hard disk storage has shown remarkable increase in capacity in the last two decades, from a few megabytes to a few terabytes, while the device itself has remained roughly the same size.
