Is your Windows 10 PC running slower than usual? Or do you suspect your SSD might be wearing out? Don’t panic — solid-state drives (SSDs) are reliable, but like all hardware, they can degrade over time. Knowing how to check SSD health in Windows 10 helps you catch early signs of trouble before your data is at risk.
In this complete step-by-step guide, we’ll show you every method to monitor your SSD’s health, from built-in Windows tools to powerful third-party software. By the end, you’ll know exactly how to check, understand, and maintain your SSD for top performance and long lifespan.
What Does SSD Health Mean?
Your SSD’s health indicates how much life it has left before it starts to fail or lose reliability.
Unlike traditional hard drives (HDDs) with spinning parts, SSDs use NAND flash memory — which can only be written and erased a limited number of times.
SSD health typically reflects:
-
Total Bytes Written (TBW): How much data has been written to the drive.
-
SMART Attributes: Self-Monitoring, Analysis, and Reporting Technology metrics that track errors, wear levels, and performance.
-
Remaining Life Percentage: The manufacturer’s estimate of how much usable lifespan remains.
In short, SSD health tells you how “worn out” your drive is — and whether you need to back up or replace it soon.
Why You Should Check SSD Health Regularly
Checking SSD health isn’t just for tech enthusiasts — it’s essential for data safety and system stability. Here’s why:
| Reason | Description |
|---|---|
| 🧠 Prevent Data Loss | Early detection of bad sectors or wear can help you back up data before failure. |
| ⚙️ Maintain Speed | SSD performance may drop as it fills or wears. |
| 🧩 Extend Lifespan | Proper maintenance helps reduce unnecessary writes and overheating. |
| 🔍 Plan Ahead | Monitor drive health so you can replace it before it fails unexpectedly. |

Windows includes a Drive Optimization (defrag) tool that also shows SSD condition.
Steps:
-
Type Defragment and Optimize Drives in the search bar and open it.
-
Select your SSD from the list.
-
Check the Media type — it should say “Solid state drive.”
-
Under Current status, see if the drive is “OK.”
💡 Tip: Don’t defragment SSDs — instead, let Windows automatically “optimize” them via TRIM.
Method 4: View SSD Health Using Task Manager
Task Manager gives you real-time SSD performance stats — helpful for spotting early issues.
Steps:
-
Right-click the taskbar → choose Task Manager.
-
