Thanks for your great article.

I have some questions actually on your assumption value:

"Let’s assume a 100:1 ratio between read and write."
"Let’s assume that each stored object will be approximately 500 bytes"
*Why do you assume? Is there any real-life existence of that number? How we can make the assumption to a proper value?
*

Sorry for my misunderstanding.
