What Does A Hard Drive or SSD Do On My PC?

<p>Are you wondering how a solid-state drive works? SSDs function like hard drives, but with different technology. Like USB drives, SSDs use flash memory to store data, which is accessed digitally. A hard disk drive (HDD) uses a spinning platter and an arm that moves across the platter to read each portion of data. As a result, SSDs deliver nearly instant boot and load times because they don’t have to mechanically seek out data on a spinning platter.</p>
<h2>What Does a Solid State Drive Do?</h2>
<p>Inside your computer, the storage drive (whether an SSD or an HDD)<strong> </strong>works alongside your system’s memory and processor to access and use data. Solid-state drives use different technology than traditional hard drives that allow SSDs to access data faster, improving your computer’s performance. This data includes things like your operating system, games, images, or music.</p>
<p>For example, if you want to access data from a spreadsheet and perform some basic edits, here’s what’s going on behind the scenes:</p>
<ol>
<li> Programs and files are housed on your storage drive.  In this case, the spreadsheet you want to access.</li>
</ol>

<p>2.  When you make a request to open the spreadsheet, your computer’s processor transfers the program data from your storage drive to RAM for short-term access and use. Because SSDs have nearly instant data transfer speeds, they speed up the data transfer process, which is the amount of time it takes to load programs and files. </p>

<p>3. The processor then accesses data from the memory, which acts as your computer’s bank of available workspace. Memory is then used to “run” the program.</p>

<p>In addition to being faster, SSDs are more durable because they don’t have moving parts that can be broken or wear out, especially when they’re moved around. Plus, they use less energy, saving battery life.</p>
<p>Installing an SSD is one of the easiest ways to transform almost every aspect of your system’s performance, making slow load times a thing of the past.</p>
