Your SSD is one of the most important components in a Windows PC. It stores your operating system, applications, documents, photos, and other important files. Although modern solid-state drives are generally reliable, SSDs can wear out over time or develop problems that affect performance and data safety.
Learning how to check SSD health in Windows can help you detect potential problems before they become serious. Fortunately, Windows provides several built-in tools, while third-party utilities can provide more detailed information such as drive temperature, remaining lifespan, and SMART data.
In this guide, you’ll learn several practical ways to check SSD health on Windows 10 and Windows 11.
What Does SSD Health Mean?
SSD health refers to the overall condition and expected endurance of a solid-state drive. Unlike traditional hard drives, SSDs use NAND flash memory with a limited number of write cycles.
As data is written and erased, the memory cells gradually wear down. SSD manufacturers therefore provide an estimated endurance rating, often expressed as TBW (Terabytes Written).
SSD health information may include:
- Remaining drive lifespan
- Total data written
- SSD temperature
- Available spare capacity
- SMART status
- Read and write errors
- Bad or failing memory blocks
- Firmware information
- Overall drive condition
A healthy SSD doesn’t necessarily mean it is brand new. A drive can still function normally while its estimated remaining lifespan gradually decreases.
Method 1: Check SSD Health Using Windows Settings
Windows 11 includes a basic storage health feature that can provide useful information about supported NVMe SSDs.
Step 1: Open Windows Settings
Press Windows + I to open Settings.
Step 2: Go to Storage
Select:
System → Storage → Advanced storage settings → Disks & volumes
Step 3: Select Your SSD
Find your SSD in the list and select Properties.
Depending on the drive and Windows version, you may see information about the drive’s health or reliability.
Windows’ built-in information can be useful for detecting obvious problems, but it doesn’t expose every SMART attribute or detailed endurance metric.
Method 2: Check SSD Health Using PowerShell
PowerShell provides another quick way to check whether Windows detects a storage device as healthy.
Step 1: Open PowerShell
Right-click the Start button and select Terminal (Admin) or PowerShell (Admin).
Step 2: Run the Storage Health Command
Enter:
Get-PhysicalDisk | Select FriendlyName, MediaType, HealthStatus, OperationalStatusPress Enter.
You may see results similar to:
FriendlyName MediaType HealthStatus OperationalStatus
------------ --------- ------------ -----------------
NVMe SSD SSD Healthy OKThe most important field is HealthStatus.
If Windows reports Healthy, the operating system is not currently detecting a critical physical drive-health problem.
However, this command is relatively basic. It doesn’t necessarily tell you the SSD’s remaining endurance percentage or detailed SMART values.
Method 3: Use WMIC to Check Drive Status
On some Windows systems, you can also use the Windows Management Instrumentation command line.
Open Command Prompt as Administrator and enter:
wmic diskdrive get model,statusA healthy drive may return:
Model Status
Samsung SSD OKThe OK status indicates that Windows is not reporting an immediate problem through this basic health check.
Keep in mind that this method provides only limited information and shouldn’t be considered a complete SSD diagnostic.
Method 4: Check SSD Health with a Manufacturer Tool
For detailed SSD information, the drive manufacturer’s diagnostic software is often a better option.
Many SSD manufacturers provide utilities that can display:
- SSD health percentage
- Drive temperature
- Firmware version
- Total bytes written
- SMART information
- Performance benchmarks
- Firmware updates
- Diagnostic tests
Examples include tools from manufacturers such as Samsung, Crucial, Kingston, Western Digital, and Solidigm.
If your SSD has manufacturer-specific software, it can be especially useful because the application may understand the drive’s endurance and SMART attributes more accurately than generic Windows tools.
Always download SSD utilities from the manufacturer’s official website.
Method 5: Use a SMART Monitoring Tool
SMART, or Self-Monitoring, Analysis and Reporting Technology, allows storage devices to report various operating and reliability metrics.
A SMART monitoring application can provide significantly more information than Windows’ basic health status.
Depending on your SSD, you may find attributes such as:
- Percentage used
- Available spare
- Critical warning
- Media and data integrity errors
- Total host reads
- Total host writes
- Power-on hours
- Drive temperature
- Unsafe shutdowns
- Error information
For NVMe SSDs, Percentage Used is particularly useful. It represents the estimated amount of the SSD’s endurance that has been consumed.
For example, if an SSD reports:
Percentage Used: 15%
that generally means the drive’s estimated endurance has been partially consumed, rather than indicating that only 15% of its physical storage capacity remains.
How to Check SSD Temperature
Temperature is another important part of SSD health.
An SSD that consistently operates at excessive temperatures may experience thermal throttling, reducing performance. Prolonged heat can also contribute to accelerated component aging.
You can check SSD temperature through:
- SSD manufacturer utilities
- SMART monitoring applications
- BIOS/UEFI hardware monitoring
- Some Windows storage-management tools
For many consumer SSDs, temperatures around 30°C to 50°C during light workloads are common, while temperatures can rise considerably during heavy transfers.
The exact safe operating range depends on the specific SSD model, so check the manufacturer’s specifications for accurate limits.
How to Check How Much Data Has Been Written to an SSD
Total data written is useful when evaluating SSD endurance.
Manufacturers commonly specify an endurance rating using TBW (Terabytes Written).
For example, suppose an SSD has a rated endurance of:
600 TBW
and monitoring software reports approximately:
120 TB written
The drive has consumed roughly 20% of its rated write endurance, assuming the figures are directly comparable.
However, TBW should not be treated as an exact expiration point. An SSD can continue operating beyond its rated endurance, while individual drives can also experience problems before reaching the theoretical rating.
The good news is that most SSD detection problems can be solved without replacing the drive. This guide explains the best ways to fix SSD not recognized Windows errors on desktops and laptops.
Signs That Your SSD May Be Failing
Checking health information is useful, but real-world symptoms are equally important.
Watch for these warning signs:
1. Frequent System Freezes
If Windows regularly freezes without an obvious software cause, storage problems may be involved.
2. Unexpected Blue Screens
Repeated blue-screen errors can have many causes, but storage errors are one possibility worth investigating.
3. Files Becoming Corrupted
Unexpected file corruption, missing files, or applications repeatedly reporting damaged data can indicate a storage problem.
4. Extremely Slow Performance
A sudden and persistent performance drop may indicate thermal throttling, insufficient free space, firmware problems, or an aging SSD.
5. Drive Disappearing
If the SSD randomly disappears from Windows, BIOS/UEFI, or File Explorer, investigate the drive, connection, firmware, and motherboard slot.
6. SMART Warnings
A critical SMART warning should never be ignored.
If monitoring software reports serious health problems, back up your important files immediately.
What to Do If Your SSD Health Is Poor
If Windows or a diagnostic application reports that your SSD is unhealthy, don’t wait until the drive completely fails.
Back Up Your Important Data
First, copy important files to another drive or a trusted backup location.
Check the SSD Connection
For SATA SSDs, inspect the SATA data and power connections.
For M.2 SSDs, make sure the drive is properly seated and secured.
Check for Firmware Updates
An outdated SSD firmware version can sometimes cause compatibility, stability, or performance problems.
Check Drive Temperature
Excessive temperatures can cause performance problems and may require better airflow or cooling.
Free Up Storage Space
Avoid keeping an SSD almost completely full. Maintaining reasonable free space can help Windows and the SSD’s controller manage data efficiently.
Replace a Failing SSD
If SMART diagnostics indicate serious degradation or the drive frequently disconnects, replacement is generally safer than continuing to rely on it for important data.
SSD Health vs SSD Storage Capacity
It’s important to understand that SSD health and available storage space are different things.
For example, an SSD could have:
Health: 95%
Free space: 10%
The drive may still be considered healthy even though it is almost full.
Conversely:
Health: 60%
Free space: 70%
The SSD has plenty of available storage but may have already consumed a significant portion of its estimated endurance.
Therefore, don’t judge SSD health solely by how much free space is available.
How Often Should You Check SSD Health?
For a normal home computer, checking SSD health every few months is usually sufficient.
You should check more frequently if:
- The computer contains important work files
- The SSD is several years old
- You perform large amounts of data writing
- The system has experienced unexpected shutdowns
- You notice unusual performance problems
- SMART warnings have appeared
Regular monitoring can help you identify changes before they become serious.
Does SSD Health Affect Performance?
SSD health and performance are related, but they aren’t identical.
A healthy SSD can become slower because of:
- Very low free space
- High operating temperatures
- Background workloads
- Firmware issues
- Heavy sustained writes
- Interface limitations
- Hardware configuration
Likewise, an SSD with a reduced health percentage may still perform normally.
Therefore, use both health monitoring and performance testing when diagnosing an SSD.
Should You Replace an SSD When Health Drops Below 100%?
Not necessarily.
A health percentage below 100% does not automatically mean that an SSD is failing. SSDs naturally consume endurance as data is written.
For example, an SSD showing 90% health may still have years of useful service remaining depending on workload and drive specifications.
Replacement becomes more important when you see:
- Critical SMART warnings
- Increasing media/data errors
- Frequent drive disconnections
- Corrupted files
- Severe instability
- Manufacturer diagnostics reporting failure
The most important rule is to back up important data before a failing SSD becomes inaccessible.
Final Thoughts
Knowing how to check SSD health in Windows is an easy way to monitor one of the most important components in your computer. Windows PowerShell and built-in storage tools can provide basic health information, while manufacturer utilities and SMART monitoring software can reveal much more detailed information.
For the best results, don’t rely on a single health percentage. Check the SSD’s SMART data, temperature, total writes, error information, and real-world behavior together.
Most importantly, remember that SSD health monitoring isn’t a replacement for backups. If your SSD starts showing serious warnings, back up your files first and investigate the drive afterward.
