Your SSD will not warn you before it dies — or rather, it does warn you, quietly, in a log you probably never open. Checking SSD health on Windows 10 and 11 takes under five minutes, needs no screwdriver, and tells you whether your drive is fine or living on borrowed time. Here are the three ways that actually work, and how to read the numbers without panicking.

The fastest check is built into Windows 11. Go to Settings > System > Storage > Advanced storage settings > Disks & volumes, click your drive, then Properties. The Drive health section shows a status (Healthy, Warning, or Critical) plus estimated remaining life, available spare, and temperature. One catch: this only works for NVMe SSDs on Windows 11 (22H2 and later). SATA SSDs and hard drives show nothing here. On Windows 10 the path is Settings > System > Storage > Manage disks and volumes, with briefer information.

For the full picture, use CrystalDiskInfo. It is free, open source (MIT-licensed), made by Crystal Dew World since 2008, and has passed 100 million downloads. Download the portable Standard Edition ZIP from crystalmark.info, extract it, and run DiskInfo64.exe as administrator. Each drive appears as a tab with its status and temperature. Health Status reads Good (blue), Caution (yellow), Bad (red), or Unknown (gray). A percentage such as "Good 97%" comes from remaining write life and spare capacity, and the formula differs per manufacturer. Two numbers deserve your attention: Total Host Writes and Power On Hours — they put the percentage in context.

If you would rather install nothing, Windows has two built-in commands. Open Windows Terminal as administrator (Win + X) and run wmic diskdrive get model,status — OK means no SMART threshold was crossed, Pred Fail means the firmware predicts failure. For a richer summary in PowerShell, run Get-PhysicalDisk | Select FriendlyName, HealthStatus, OperationalStatus, and for deeper counters, Get-PhysicalDisk | Get-StorageReliabilityCounter | Format-List *. Both only report threshold summaries, not the full SMART table.

Reading the SMART numbers is where most people get confused. On NVMe drives, watch Percentage Used (the share of rated write endurance consumed), Available Spare (reserve NAND blocks, normally 100%), Media and Data Integrity Errors (must be 0), and Critical Warning (must be 0). On SATA drives, the key attributes are 05 Reallocated Sectors Count (ideally 0), C5 Current Pending Sector Count, C6 Uncorrectable Sector Count, and C7 UDMA CRC Error Count — the last one usually means a bad SATA cable, not a bad drive. One trap: raw values in CrystalDiskInfo default to hexadecimal. Switch them to decimal (Function > Advanced Feature > Raw Values > 10 [DEC]) before concluding anything.

So what percentage is safe? Above 90% is very healthy, 80–90% is normal for a drive used two or three years, 50–80% means start planning a replacement, and below 50% — or any Caution status — means back up now. The trend matters more than the number: health dropping 2% a month is far more alarming than a stable 70%.

I ran the TBW math myself to put the percentages in perspective. A 1 TB NVMe SSD rated at 600 TBW, writing 20 GB a day, lasts about 82 years; even at 100 GB a day it lasts 16 years. A 500 GB SATA SSD rated at 300 TBW lasts 16 years at 50 GB a day. Normal use of 10–20 GB a day will practically never exhaust the TBW rating before you replace the drive for other reasons. A 97% health reading after two years is normal, not a warning.

One honest finding from my own testing: when I tried reading SMART with smartctl on my virtual machine, it failed completely — Unable to detect device type — because the virtual disk does not forward SMART to the guest. That is exactly what "Unknown" means in CrystalDiskInfo: the read path is blocked, not the drive broken. The same happens with SSDs in USB enclosures or behind RAID controllers. Move the SSD to an internal slot and check again before worrying.

If you see a Bad status, a non-zero Critical Warning, media errors above zero and climbing, or sustained temperatures over 70°C, back up first and diagnose later. Do not run heavy benchmarks on a failing drive.
