In 1957 a 0.00098 KB RAM cost $392.
In 1955 the amount of ROM on an IBM hard-drive was 12 MB and $74800
In 1981, an 18 MB hard drive cost $2500.
In 1990 RAM costs were $50 per MB. At this cost it was $00.0047 per byte.
In 2000 the 2 GB of RAM cost just about $50, which is $00.00000000000174
The price and capacities of RAM and hard drive storage have come a long way in the past 30 years. Based on the information I believe that price of RAM will be able to buy a 100 TB hard drive in the years 2020. How I came to those years is right now in 2013 we are able to buy a 5 TB hard drive and the number is increasing rapidly year by year so with those numbers that is my prediction. As of right now for a hundred dollars you can purchase 8 GB’s of RAM, ten years ago you could purchase 1 GB of RAM for around two hundred dollars, so my prediction is how much RAM could be brought in ten years for a hundred dollars and around 16 GB’s of RAM based on previous prices on RAM. Also as of right now you can purchase a 1 TB hard drive for around a hundred dollars depending on the make and model, so in ten years I think we will also have about a 100 TB hard drive. So in ten years I believe based on prices on hard drives within the past that for a hundred dollars you will be able to buy a 50 TB hard drive. RAM prices being so cheap right now, a hundred dollars goes pretty far, and if you can afford to double that hundred dollars to two hundred dollars you’ll find to buy not only enough RAM to fill your notebook or desktop, but you can live with a smaller sized boot drive you can also upgrade to a SSD for even more savings.
