How to Check SSD Health
Short answer
You can check SSD health without buying anything: Windows has a built-in SMART status query, and most major drive makers ship a free health tool. What matters is the trend and the warnings — not a single scary-looking number.
Method 1 — the built-in quick check (no install)
Open PowerShell and run:
Get-PhysicalDisk | Select-Object FriendlyName, MediaType, HealthStatusHealthy— the drive reports no SMART issues right now.Warning— investigate with the manufacturer’s tool before trusting it with important data.- If you are not sure which entry is your system drive, match it with your drive’s advertised name/capacity.
This is a status light, not a full report. For details, use method 2.
Method 2 — manufacturer tools
Major SSD brands provide free utilities (often branded as SSD dashboards) that read SMART data in detail and can run firmware checks. Downloading the tool from the drive manufacturer’s official site — matched to your drive’s brand — is the most reliable route. If you do not know your drive’s brand, run the PowerShell command above; FriendlyName usually reveals it.
What to watch for
- SMART warning / “bad” health status — treat as a real signal; back up first.
- Failing to initialize errors, unexplained disconnects, or files that corrupt — symptoms that deserve attention even if a quick check says “healthy”.
- Percentage used / lifespan indicators — a wear estimate, not a countdown. Different tools compute them differently, so avoid dramatic conclusions from one number.
What health checks do NOT tell you
They do not measure your day-to-day speed, and they do not explain slowness caused by a full drive or background software. Run Why is my SSD slow? checklist if health looks fine but the machine does not feel fine.
When to use the tool
The Should I Replace My SSD? tool includes drive errors as an input and routes you to “investigate first” rather than “buy now” — which is exactly the right order of operations.
