Hard Disk Historical Pricing (found from Kryder’s Law – A rule of thumb for hard drive growth).

It’s amazing that in March of 1986, $48/MB was the sweet spot for a hard drive.

By other milestones in my life:

By the time I started college in 1994, the cost was under $1 per MB.

By the time I started my first full time job in late 1999, the price for hard drives was $20 per GB!   (The cost of “high grade” flash memory now).

When my first daughter was born in August 2004, the price per GB was near $1.

When my son was born in August 2008, I remember seeing drives for 5 GB per $1.

Now, you can get about 10 GB per $1.  Even the large solid state hard drives are only $2 per GB, but yet I’ve been in conversations about how we could not imagine paying “that much” for them.
