Over the past 30 years the cost of Electronics has steadily decreased. The cost of electronic storage has decreased greatly over the past 30 years as well. In this paper I will be talking about the decrease in the cost of RAM and Hard Drive Storage, how much will a 100TB HDD will cost when it becomes widely available in the future, and how much memory I will be able to buy with $100 in 10 years. In 1956, IBM created the first commercial Hard Drive called the IBM 305 RAMAC which held 5MB and cost a whopping 50 thousand dollars! Electronic storage started being more widespread during the early 1980’s, but it wasn’t until the 1990s that RAM and Hard Drive Storage begin to be cheap enough for the average person. Back in 1981 the price for one MB of Hard Drive storage space was $340! Most people couldn’t afford a computer back in the 1980’s because of the huge cost. Through the 1980’s the cost per MB fell from around $340 during 1981 then to $40 per MB in 1988, and finally to $9 per MB in 1990.
The cost of one Bit of ram in 1981 was 0.000425 cents, in 1988 it was 0.000005 cents, in 1995 it was 0.000000158 cents, in 2000 the cost per Bit was 0.000000063, and in 2013 the cost per Bit was 7.9×10^-10 cents. To get an understanding of how much memory will cost in the future and when 100TB hard drives will become commercially available, we have to take a look at how the price for memory has gotten cheaper over the past 10-30 years, the ever increasing amount of storage space that can be squeezed onto a hard drive platter, and take in to account the rapid growth in the technology field. According to Chris Mellor in his article (http://www.theregister.co.uk/2013/11/01/hp_memristor_2018/) technology giant HP announced that 100TB hard drives could be available as early as 2018.
I firmly believe that in 4 years by 2018 there will be 100TB drives for sale to the public but they will probably be very expensive till they go into mass production. In 10 years, we will be able to buy a hard drive with a phenomenal amount of storage space. From 1990 to 2014 the price has gone down exponentially from $9 per MB to under 150 MB per Cent! If we follow that exponential trend we are looking at hard drives that can hold over 100TB that cost fewer than 100 dollars, while the RAM will decrease in price slower. In conclusion, the cost of Storage such as RAM and Hard Drives has gotten very cheap, from over $500 per MB to 5 cents per GB! We will see a continual decrease in the cost of electronic storage and an increase in the amount of storage in smaller packages.
