An SSD can continue working normally even while its flash memory is wearing down or its internal controller is recording reliability problems. That is why checking SSD health is more useful than waiting for obvious symptoms such as freezing, corrupted files, failed startups, or a drive that suddenly disappears from Windows.
Modern SSDs track internal health information through SMART and related drive telemetry. Depending on the SSD and connection type, this data can reveal its overall health status, estimated remaining life, temperature, available spare capacity, media errors, and total data written.
If you want to know how to check SSD health on a laptop or PC, Windows provides several useful starting points. For deeper information, you may also need the SSD manufacturer’s diagnostic software because Windows does not expose every health attribute for every type of SSD.
Key Takeaways
- Check SSD health before symptoms become serious, particularly on older or heavily used computers.
- Windows PowerShell can quickly show whether Windows considers a physical disk Healthy, Warning, Unhealthy, or Unknown.
- Windows 11 can display detailed health information for supported NVMe SSDs, including estimated remaining life, available spare capacity, and temperature.
- SMART monitoring provides more useful information than simply checking how much free storage remains.
- If an SSD reports reliability warnings or starts producing file errors, back up important data before attempting repairs.
Pro Tip
Do not judge SSD condition from a single percentage alone. A drive showing a high remaining-life figure can still develop controller, firmware, NAND, or connection problems. Check health status, remaining life, temperature, error counts, and real-world symptoms together before deciding that an SSD is healthy.
What Does SSD Health Actually Mean?
SSD health refers to the condition and reliability of the physical solid-state drive rather than how much storage space is available.
A nearly full SSD is not automatically unhealthy.
Likewise, an SSD with plenty of free space can still have hardware problems.
SSD health monitoring can include several factors:
Remaining flash endurance
NAND flash cells have a finite write endurance. SSD controllers track usage to estimate how much rated life remains.
Available spare capacity
SSDs reserve spare flash memory that can replace blocks that become unusable.
Temperature
Excessive operating temperatures can affect performance and long-term reliability.
Media or data errors
Repeated internal errors may indicate deteriorating storage or controller problems.
Operational status
Windows or the SSD controller may flag a drive when reliability has fallen below an expected threshold.
This makes an SSD health check very different from simply opening File Explorer and looking at the amount of free space.
How to Check SSD Health in Windows 11
Windows 11 includes a built-in storage-health view for supported drives.
Open:
Settings > System > Storage > Advanced storage settings > Disks & volumes
Select the SSD you want to inspect and open Properties.
For supported NVMe SSDs, Windows can display health information such as:
- Estimated remaining life
- Available spare capacity
- Current temperature
- Critical storage warnings
Microsoft notes that this detailed native storage-health monitoring applies to NVM/NVMe SSDs rather than SATA SSDs or traditional hard drives.
That distinction matters.
If you have a SATA SSD and Windows does not show an estimated-life percentage in this area, it does not necessarily mean Windows cannot detect the drive or that something is wrong with it. You may need the manufacturer’s SSD utility or another SMART-compatible monitoring tool for more detailed information.
How to Check SSD Health Using PowerShell
PowerShell provides one of the quickest ways to check how Windows currently classifies your physical drives.
Right-click Start and open Terminal or PowerShell.
Enter:
Get-PhysicalDisk
Press Enter.
Windows should return information similar to:
| FriendlyName | MediaType | OperationalStatus | HealthStatus |
| NVMe SSD | SSD | OK | Healthy |
| SATA SSD | SSD | OK | Healthy |
Microsoft’s Storage PowerShell module defines drive health values including Healthy, Warning, Unhealthy, and Unknown.
What Does Healthy Mean?
If the drive shows:
HealthStatus: Healthy
and:
OperationalStatus: OK
Windows is not currently reporting a storage-management health problem for that physical disk.
However, this is a high-level status.
It does not tell you everything about NAND wear, total writes, individual SMART attributes, temperature history, or drive-specific error counts.
What If It Shows Warning?
A Warning status deserves investigation, especially if the laptop or PC is also experiencing freezing, file corruption, unusually slow disk access, or boot problems.
Back up critical data before performing extensive troubleshooting.
What Does Unknown Mean?
Unknown does not automatically mean the SSD has failed.
Windows may not be receiving enough health information from the storage device, controller, enclosure, driver, or storage-management provider to classify it properly.
This is common enough that an Unknown result should be investigated using another diagnostic method rather than interpreted immediately as drive failure.

How to Check Which SSD Is Installed
Before checking manufacturer-specific health information, determine exactly which SSD model your laptop or PC contains.
Open:
Task Manager > Performance > Disk
The drive model may appear near the top of the window.
You can also use PowerShell:
Get-PhysicalDisk
or open:
Device Manager > Disk drives
Knowing the exact SSD model is important because two laptops with the same overall specifications may contain drives from different manufacturers.
If you also need to identify your processor, RAM, graphics hardware, and storage configuration, see our guide on how to check the specifications of a laptop.
What Is SMART SSD Health?
SMART stands for Self-Monitoring, Analysis and Reporting Technology.
SSDs use internal monitoring data to keep track of conditions that can help indicate wear or reliability problems.
The exact SMART attributes vary between manufacturers.
Common SSD health data can include:
- Power-on hours
- Total data written
- Percentage used
- Remaining life
- Temperature
- Media errors
- Unsafe shutdowns
- Available spare blocks
This information can be considerably more useful than a simple Healthy or Unhealthy result.
For example, two SSDs could both report Healthy while one has operated for only 500 hours and another has accumulated years of continuous use and substantially more NAND writes.
What Does SSD Health Percentage Mean?
Some SSD utilities display a value such as:
Health: 96%
or:
Remaining Life: 82%
This usually represents an estimate based largely on the manufacturer’s endurance model and recorded drive usage.
It should not be interpreted as a precise countdown.
A drive at 80% health does not mean it will fail after another exact 80% period of time.
Microsoft describes estimated remaining life as a manufacturer-based approximation of drive life rather than a guaranteed failure timer.
For that reason, SSD health percentage is most useful as a trend.
If the value falls unusually quickly or appears alongside other warnings, further investigation is appropriate.
SSD Health vs SSD Performance
A slow SSD is not always a failing SSD.
Performance can drop for reasons unrelated to hardware health.
For example, an SSD may feel slower when:
- Very little free space remains.
- Windows is performing heavy background activity.
- Large updates are being installed.
- The SSD is overheating and throttling.
- The system has insufficient RAM.
- Antivirus software is heavily scanning files.
- The SSD is connected through a slower interface.
Conversely, a failing SSD may still benchmark reasonably well shortly before more serious problems occur.
This is why SSD health and SSD speed should be checked separately.
What SSD Temperature Is Too High?
SSD temperature varies by drive design, workload, airflow, and whether the device is SATA or NVMe.
NVMe SSDs can become particularly warm during sustained transfers because their controllers operate at high speeds in a compact area.
Instead of relying on one universal temperature limit, check the operating-temperature specification published for your particular SSD.
The important warning signs are sustained temperatures near or beyond the manufacturer’s rated range, repeated thermal throttling, or unusually high idle temperatures.
On laptops, poor ventilation, dust accumulation, blocked intake vents, or a missing thermal pad can contribute to higher SSD temperatures.
What Is Available Spare on an SSD?
SSDs contain spare NAND capacity that the controller can use when storage blocks wear out or become unreliable.
Windows can show Available spare for supported NVMe SSDs.
Microsoft describes this as a normalized percentage representing the remaining spare capacity available to the SSD.
A critical warning may appear when spare capacity falls below the manufacturer’s defined safety threshold.
If that happens, treat the situation seriously.
Copy important files to another drive or backup location before continuing to use the SSD for important data.
Common Signs an SSD May Be Failing
SSD failures do not always look the same.
Unlike a mechanical hard drive, an SSD normally will not produce clicking or grinding noises.
Instead, you may experience problems such as:
Windows repeatedly freezing during disk activity
If the computer freezes specifically while opening, copying, or saving files, storage deserves investigation.
Files becoming corrupted
Repeated unexplained file corruption can indicate storage problems, although RAM, software, and file-system issues can produce similar symptoms.
Windows takes unusually long to start
A sudden change in boot behavior can be worth investigating, particularly when combined with disk errors.
The SSD disappears intermittently
If the drive occasionally disappears from BIOS, Disk Management, or Windows, there may be an SSD, controller, connection, firmware, or motherboard problem.
The drive becomes read-only
Some SSDs can enter a read-only state when serious reliability problems occur. Microsoft includes a drive becoming read-only among the critical storage warnings Windows can report.
SMART or Windows reports a warning
Do not ignore a reliability or predictive-failure warning simply because the computer still seems to operate normally.
Does CHKDSK Check SSD Health?
Not in the same way as SMART monitoring.
CHKDSK primarily checks the Windows file system and volume for logical or structural problems.
For example:
chkdsk C: /scan
can check a Windows volume for file-system issues.
But a successful CHKDSK result does not prove that the physical SSD is healthy.
An SSD can have a clean NTFS file system while its internal health telemetry indicates declining NAND endurance or hardware errors.
Likewise, a healthy physical SSD can contain file-system corruption caused by an unsafe shutdown or software problem.
Use SMART or drive-health data to evaluate the physical SSD and file-system tools for logical volume problems.
Should You Still Use WMIC to Check SSD Health?
Older SSD guides frequently recommend a command such as:
wmic diskdrive get status
That approach is increasingly outdated on modern Windows systems.
For current Windows machines, PowerShell’s storage commands such as:
Get-PhysicalDisk
provide a more appropriate built-in method for obtaining physical-disk health information.
For detailed SSD-specific values, use the drive manufacturer’s current diagnostic utility when available.
Use the SSD Manufacturer’s Software for Deeper Checks
Windows gives you a useful overview, but manufacturer utilities can often read more detailed information from the SSD.
Depending on the manufacturer and drive, the utility may provide:
- SSD health percentage
- Firmware version
- Total bytes written
- Temperature
- SMART attributes
- Diagnostic tests
- Drive optimization
- Firmware updates
Use software from the SSD manufacturer or another trusted storage diagnostic provider rather than downloading unknown “SSD repair” utilities.
Firmware updates should also be handled carefully. Keep important files backed up and follow the manufacturer’s instructions for the exact drive model.
How Often Should You Check SSD Health?
There is little benefit in obsessively checking a healthy SSD every day.
For an ordinary laptop or desktop, occasional checks are usually enough.
A health check becomes more important when:
The SSD is several years old.
The computer handles heavy write workloads.
The SSD stores important business data.
The machine is behaving unusually.
Windows reports a storage warning.
You are preparing to reuse or redeploy an older computer.
You plan to rely on the system for an important event, project, or presentation.
The more important the data is, the more important regular backups are. SSD-health monitoring should complement backups, not replace them.
What to Do If SSD Health Is Bad
If Windows, SMART data, or the manufacturer’s utility reports serious health problems, protecting the data should be the first priority.
Do not begin by running repeated benchmarks, large write tests, formatting the drive, or reinstalling Windows.
Instead:
Back up irreplaceable files.
Confirm that the backup can actually be opened.
Reduce unnecessary writes to the SSD.
Check whether the manufacturer provides a diagnostic test.
Plan to replace the drive if the reliability warning is confirmed.
If the SSD is already producing read errors or repeatedly disconnecting, further use may increase the risk of losing accessible data.
Can You Repair Bad SSD Health?
Usually, you cannot restore worn NAND flash to new condition through software.
If an SSD’s health percentage has fallen because the flash has consumed part of its rated write endurance, formatting the drive will not reset that physical wear.
Likewise, deleting files or reinstalling Windows will not restore consumed NAND endurance.
Some apparent SSD problems can be caused by firmware, drivers, overheating, a loose connection, or file-system corruption rather than actual NAND failure. Those issues may be fixable.
The key is determining whether the warning relates to the physical SSD or something around it.
SSD Health for Business Laptops and PCs
Checking one drive manually is manageable. Checking the storage health of a large number of older computers before a temporary deployment can take considerably more time.
A business preparing laptops for training, a short-term project, an exhibition, or a temporary workforce needs more than enough storage capacity. The machines also need reliable SSDs, sufficient RAM, compatible software, and a consistent hardware configuration.
For temporary deployments, laptop rental can provide SSD-equipped laptops configured for the workload rather than requiring an organization to upgrade or troubleshoot an existing fleet.
For projects requiring a wider combination of technology, IT rental can cover laptops alongside other equipment required for temporary business and event deployments.
Conclusion
Knowing how to check SSD health on a laptop or PC can help you identify storage problems before they develop into a complete drive failure.
Start with Windows 11’s storage settings if you have a supported NVMe SSD. Then use PowerShell and the Get-PhysicalDisk command for a quick overview of physical-disk health. For deeper information such as detailed SMART values, total writes, firmware status, and drive-specific endurance, check the SSD manufacturer’s diagnostic software.
Do not rely on only one number. Remaining life, available spare capacity, temperature, SMART errors, Windows warnings, and real-world symptoms should be considered together.
Most importantly, a Healthy result is not a substitute for a backup.

FAQs
How Do I Check My SSD Health in Windows 11?
Go to Settings > System > Storage > Advanced storage settings > Disks & volumes, select the SSD, and open its properties. Supported NVMe SSDs can show information such as estimated remaining life, available spare capacity, temperature, and critical warnings. You can also run Get-PhysicalDisk in PowerShell for a quick health-status check.
Is 80% SSD Health Still Good?
An 80% remaining-life reading usually means the SSD has consumed part of its manufacturer-rated endurance rather than that failure is imminent at a precise point. Check whether the drive also reports errors, low spare capacity, excessive temperatures, or reliability warnings. The percentage should be treated as an estimate and trend rather than an exact failure countdown.
How Do I Know If My SSD Is Failing?
Warning signs can include repeated file corruption, freezes during storage activity, unusually slow startup, the SSD disappearing intermittently, SMART warnings, reliability warnings, or the drive becoming read-only. Back up important files promptly if several of these symptoms occur together.
Does Formatting an SSD Restore Its Health?
No. Formatting changes the file system and removes existing data structures, but it does not restore NAND cells that have already consumed part of their rated endurance. A drive showing physical wear will not return to 100% health simply because it has been formatted.
Can an SSD Show Healthy and Still Fail?
Yes. Health monitoring reduces uncertainty but cannot predict every possible controller, firmware, electrical, or sudden hardware failure. An SSD can report Healthy and still develop an unexpected problem, which is why important files should always exist in a separate backup.
