Your SSD knows how healthy it is. Every solid state drive tracks its own wear, errors, and remaining life, and Windows can read that data in under two minutes with tools already on your machine. Here is how to check, what the numbers actually mean, and the warning signs that mean you should act now rather than after the drive quits.
Open PowerShell (right-click the Start button and choose Terminal or PowerShell) and run:
Get-PhysicalDisk | Get-StorageReliabilityCounter | Format-List
Look at three values: Wear (percentage of rated write endurance used; under 50 is comfortable, over 80 means plan a replacement), Temperature (sustained readings over 70C shorten SSD life), and ReadErrorsUncorrected (this should be zero; any nonzero number is a drive telling you it has failed to return data correctly, and that is serious).
Windows 11 also surfaces a simpler version for NVMe drives at Settings → System → Storage → Advanced storage settings → Disks & volumes: click your drive, choose Properties, and check the Drive health section, which shows estimated remaining life and available spare. And for the fullest picture, the free tool CrystalDiskInfo reads every SMART attribute your drive reports and boils it down to a status: Good, Caution, or Bad. Caution means bad sectors or reallocated blocks exist. That is your early warning, and it is the single most useful signal a home user can get.
SMART data is useful, but SSDs are also famous for failing faster than their statistics suggest. These behaviors outrank a green health reading:
Here is the part that matters most, and it is the honest reason this page exists: SSDs usually die without warning and without the recovery options hard drives have. When a spinning drive fails, the platters still hold the data and recovery is often possible. When an SSD's controller fails, the data is encrypted behind a dead chip, and recovery ranges from expensive to impossible. The health check above is not trivia. It is the only advance notice you get.
One thing, today: back up. Everything after that can wait a day; the backup cannot. Then bring the machine in. Our $75 diagnostic (credited toward the repair) reads the drive's full SMART history, confirms whether the wear is stable or accelerating, and if replacement is the right call, we clone your data to a new SSD while the old one still reads, which is a routine job on a healthy-enough drive and a data recovery project on one that waited too long. The difference in cost between those two paths is roughly ten to one, and the only variable is when you act. If you are replacing anyway, it is also the natural moment for a capacity or speed upgrade; our SSD upgrade guide covers what is worth putting in.

How do I check SSD health in Windows without installing anything?
Run Get-PhysicalDisk | Get-StorageReliabilityCounter | Format-List in PowerShell, or on Windows 11 with an NVMe drive, check Drive health under Settings, System, Storage, Advanced storage settings, Disks and volumes. Both read the drive's own self-reported data.
What percentage of SSD life is bad?
Wear under 50 percent is comfortable. Over 80 percent, plan a replacement on your schedule instead of the drive's. But behavior outranks percentages: corruption, freezes, or failed updates on a drive with a good reading still mean trouble.
Can a failing SSD be repaired?
No. Unlike some hard drive failures, SSD wear and controller failure are not repairable. The move is cloning your data to a new drive while the old one still reads. After a controller fails outright, recovery options narrow sharply and costs rise.
How long do SSDs last?
Most quality SSDs outlive the laptop around them, five to ten years of typical use. Heat, chronic near-full capacity, and heavy write workloads shorten that. The health check above tells you where your specific drive sits rather than guessing from averages.
