caching - Chrome memory cache vs disk cache

Question

I am interested in chrome memory cache vs disk cache? I use webpack, common chunks plugin and generate all my files with chunkhash.

How does memory differ from disk cache. When I reload my page some files are loaded from memory cache and some from disk cache (bundle.js and image.jpg from memory cache and css from disk cache). Sometimes it's different. Can we control that, choose what gets loaded from where? Memory cache seems to be faster than disk cache.

Like their names said:

"Memory Cache" stores and loads resources to and from Memory (RAM). So this is much faster but it is non-persistent. Content is available until you close the Browser.

"Disk Cache" is persistent. Cached resources are stored and loaded to and from disk.

Simple Test: Open Chrome Developper Tools / Network. Reload a page multiple times. The table column "Size" will tell you that some files are loaded "from memory cache". Now close the browser, open Developper Tools / Network again and load that page again. All cached files are loaded "from disk cache" now, because your memory cache is empty.
