Why primary storage is much more expensive than secondary storage?
#1
Hi friends,

I am wondering, why just a bunch of gigs in RAM cost much more than a bunch of gigs in secondary storages. is it about how the RAM works vs HDD,SSD,etc. works? or is it about the materials use to make those storages?

RAM is ridiculously inexpensive compared to processors.  RAM silicon sells for pennies per square millimeter, whereas CPU silicon sells for dollars.

All Silicon transistors are ridiculously inexpensive compared to a few years ago.

By what measure are you considering RAM to be expensive?
