What is the difference between "Flush Magento Cache" and "Flush Cache Storage" in magento's cache management?
Magento Solutions
Solution 1 - Magento
Sometimes the cache location (like /tmp/) or service (like Memcache) is shared with other applications. "Flush Magento Cache" removes only those entries that Magento reliably tracks as its own. "Flush Cache Storage" clears everything but might affect other applications if they're using it.
Normally the location is var/cache/ in Magento's folder so is not shared after all. It is safe to use either button. Sometimes (rarely) entries are not clearly tagged or Magento loses track of them and only the second button has an effect on them. I tend to use the second button when I'm having difficulty tracking down the cause of a problem.

Flush Magento Cache
Removes all items in the default Magento cache (var/cache) and the var/full_page cache that have a Magento tag
Flush Cache Storage
Removes all items in the cache. This is the equivalent of deleting the entire contents of the cache folder on the server.If your system uses an alternate cache location, any cached files used by other applications will be removed.
Solution 3 - Magento
As a practical example, if you use magento's cache for your own devices, eg;
$cache = Mage::app()->getCache();
$cache->save("My cached text","cache_name",array("my_cache"),60*60*24);
echo $cache->load("cache_name");
You will need to use flush cache storage to clear this if you make an update.
In my case it's for a dynamically generated 3 level off canvas menu.
