title: Write-back vs Write-Through caching?
body: <p>My understanding is that the main difference between the two methods is that in &quot;write-through&quot; method data is written to the main memory through the cache immediately, while in &quot;write-back&quot; data is written in a &quot;later time&quot;.</p>
  <p>We still need to wait for the memory in &quot;later time&quot; so What is the benefit of &quot;write-through&quot;?</p>
