What Is an SSD, and Why Does It Make Your PC Feel Faster?
SSDs are the single biggest upgrade most people can make. Here's how they work and why they transform an old computer.
If your computer feels slow, the culprit is often the storage drive — not the processor.
SSD vs hard drive
A hard drive (HDD) stores data on spinning platters. An SSD has no moving parts, so it reads and writes data far faster.
Note
Most slowdowns people blame on "an old CPU" are actually a slow hard drive.
Why it feels faster
Boot times, app launches, and file transfers all depend heavily on drive speed — exactly where SSDs shine.
