Check SSD Health on Windows

  1. 1

    Windows Storage Health (Windows 10/11 built-in)

    Settings → System → Storage → Advanced storage settings → Disk and volumes. Click on your SSD → Properties. Windows shows Health status and estimated remaining life if supported.

  2. 2

    Use CrystalDiskInfo (free, most detailed)

    Download CrystalDiskInfo from crystalmark.info. It is free and safe. Open it — your drives are listed with their health status (Good, Caution, Bad) and all SMART data attributes. Key values to check: Reallocated Sectors Count, Uncorrectable Error Count, and SSD-specific: Wear Leveling Count and Total Bytes Written (TBW).

Check SSD Health on Mac

  1. 3

    System Information → Storage → SMART Status

    Click the Apple menu → hold Option → System Information. Click Storage in the left panel. Select your drive. Look for SMART Status — Verified means healthy. Failing means replace immediately. If SMART Status does not appear, the drive does not support SMART reporting.

  2. 4

    Disk Utility

    Open Disk Utility (Applications → Utilities). Select your drive → click First Aid → Run. This checks for filesystem errors (not a full health check, but catches common issues).

Warning Signs of a Failing SSD

  • Files becoming corrupted spontaneously
  • Computer freezing or crashing, particularly when writing files
  • System becoming very slow, especially on boot
  • Files or folders disappearing randomly
  • Bad blocks reported in CrystalDiskInfo (any amount is a warning)
  • SMART Status showing Caution or Failing
If health shows Caution or Bad — back up immediatelyA failing SSD can fail completely and suddenly. If you see any warning status, back up all your data immediately before the drive fails completely. Do not wait.

Frequently Asked Questions

Modern SSDs typically last 5–10 years under normal consumer use. SSDs have a rated Total Bytes Written (TBW) limit — typically 150–600TB for consumer drives. At typical write rates of 20–40GB per day, a 150TB TBW drive takes over 10 years to reach its limit. Age (electrolytic capacitor degradation) is often a bigger factor than write cycles for consumer use.
Generally no — SSDs cannot be meaningfully repaired once NAND flash cells fail. If a drive shows warning signs, back up data and plan for replacement. Data recovery from a failed SSD is possible but expensive ($500–2,000+ from professional data recovery services). This is why regular backups are essential.
