&lt;p&gt;Anyone who&amp;rsquo;s swapped in an SSD knows the feeling — boot time goes from a minute to ten seconds, apps launch instantly, the whole computer feels like a different machine.&lt;/p&gt;
&lt;p&gt;The speed gap between SSD and HDD is just that big.&lt;/p&gt;
&lt;h2 id="how-they-work"&gt;How They Work&lt;/h2&gt;
&lt;h3 id="hdd-hard-disk-drive"&gt;HDD (Hard Disk Drive)&lt;/h3&gt;
&lt;p&gt;An HDD has actual metal platters spinning inside it. A read/write head moves back and forth above the platters — kind of like a record player.&lt;/p&gt;</description></item><item><title>Why USB-C Took Over Everything</title><link>https://joeyang1412.github.io/hugo-theme-spectra/posts/tech-knowledge/usb-c/</link><pubDate>Tue, 15 Apr 2025 00:00:00 +0000</pubDate><guid>https://joeyang1412.github.io/hugo-theme-spectra/posts/tech-knowledge/usb-c/</guid><description>&lt;h2 id="the-old-days"&gt;The Old Days&lt;/h2&gt;
&lt;p&gt;A decade ago, leaving the house meant carrying a pile of cables. One Micro USB for the phone, a Mini USB for the camera, a barrel plug charger for the laptop, an HDMI for the external monitor, and a USB-A flash drive. Every cable looked different, and borrowing one from someone was never straightforward.&lt;/p&gt;
&lt;p&gt;Now a single USB-C cable handles most of it. Charging, file transfers, display output, audio — all through the same port.&lt;/p&gt;</description></item><item><title>OLED vs LCD — What's Actually Different</title><link>https://joeyang1412.github.io/hugo-theme-spectra/posts/tech-knowledge/oled-vs-lcd/</link><pubDate>Tue, 01 Apr 2025 00:00:00 +0000</pubDate><guid>https://joeyang1412.github.io/hugo-theme-spectra/posts/tech-knowledge/oled-vs-lcd/</guid><description>&lt;h2 id="the-short-answer"&gt;The Short Answer&lt;/h2&gt;
&lt;p&gt;OLED looks gorgeous — high contrast, fast response, deep blacks. But it&amp;rsquo;s pricier and has burn-in risk. LCD is cheaper and more durable, but blacks look grayish and viewing angles aren&amp;rsquo;t as good. If you&amp;rsquo;ve got the budget, go OLED. If longevity matters more, stick with LCD.&lt;/p&gt;
&lt;h2 id="they-light-up-completely-differently"&gt;They Light Up Completely Differently&lt;/h2&gt;
&lt;p&gt;This is the fundamental difference.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;LCD&lt;/strong&gt; (Liquid Crystal Display) can&amp;rsquo;t produce light on its own. It needs a backlight panel behind it, and the liquid crystal layer controls how much light passes through — kind of like blinds controlling sunlight.&lt;/p&gt;</description></item></channel></rss>
