+				<h2>Reads shouldn't write!</h2>
+				<p>Another personal opinion, and change is to enable noatime, and nodiratime. Be careful with this change! And ignore if you followed my Debian install guide, as they're already enabled.</p>
+				<p>Basically without these, when a file is opened (read) on your filesystem, a write is invoked to update the time it was opened, which causes unwanted writes, and CPU cycles.</p>
+				<p>Open your fstab file</p>
+				<pre><code>sudo vim /etc/fstab</code></pre>
+				<p>And edit your mounted drive(s) to include these flags</p>
+				<pre><code>UUID=&lt;YOUR-UUID&gt;    /    ext4    noatime,nodiratime    0 1</code></pre>
+				<p>The above uses an example, make your EXISTING lines look kinda like the above. Essentially just  adding <strong>noatime, nodiratime</strong></p>

 				<h2>Server maintance notes</h2>
 				<p>Keep the server up-to date as much as possible</p>
 				<p>Only install things that you need. If this is a server for learning, half ignore this, but for production servers only install services, and make changes that are required.</p>
