I have almost fully recovered from my hard drive crash on October 3.  The new drive is amazing.  It is a Seagate 1 terabyte drive which is half solid state memory and cost right about $90. While looking for a photo I found a 5 terabyte drive for about a $100.

The first hard drive was made by IBM in 1956.  It was 5 megabytes and cost $50,000.  So I’m doing the math and I think the price per unit of storage has dropped by a factor of fifty-million in about 60 years.  The size per unit of storage has shrunk by several billion. What an amazing time we live in.

The original IBM hard drive was the size of two large refrigerators.  It was a vast improvement over tape drive storage.
