Hard drives used to be really expensive. Now they’re really cheap. You probably already know that, but Ivan Smith’s web site really hammers the point home by tracking the falling prices of storage from about 1980 through mid-2010.
In a nutshell, 30 years ago you would have had to pay about $300,000 for 1 gigabyte of storage. Last summer you could pick up 1TB drive for about $71, which means that a gigabyte of storage cost about $0.08. Sure, you’re not likely to actually find a 1GB hard drive for 8 cents anytime, but to be honest, you’d be lucky to find anyone selling a 1GB hard drive. They just don’t make them that small anymore.
