I think there is a mistake in ‘Write-through’. From what I understood, it takes more time because it write to both cache and data store. You wrote we don’t need to write to data store in last sentence. Please correct me if I am wrong.

Also I loved the way you put more resources to help. However, please limit the number of resources shown. Try to only put those which are somewhat related to the post. It makes your blog more clean and precise.
