How to Check Your SSD Health

SSDs wear out over time as data is written and erased from memory cells. Monitoring your SSD's health helps you detect potential failures before they cause data loss and determine when replacement is necessary.

1. Check built-in Windows drive health. Open Command Prompt as administrator and run 'wmic diskdrive get status'. Look for 'OK' status next to your drives. For detailed SMART data, run 'fsutil fsinfo sectorinfo C:' replacing C: with your drive letter. This shows basic health metrics and error counts.
2. Use Disk Utility on macOS. Launch Disk Utility from Applications > Utilities. Select your SSD from the sidebar and click the Info button (i). Check the S.M.A.R.T. Status field which should show 'Verified'. For more details, hold Option and click the Apple menu, then System Information > Storage to see drive condition and cycle count.
3. Install CrystalDiskInfo for comprehensive monitoring. Download and install CrystalDiskInfo from the official website. Launch the application to see your SSD's health status, temperature, total host writes, and wear leveling count. The health status appears as Good, Caution, or Bad with color coding. Check the 'Health Status' percentage and 'Total Host Writes' values.
4. Monitor key SMART attributes. Focus on critical SMART values: Wear Leveling Count shows remaining life percentage, Total LBAs Written indicates usage intensity, and Temperature readings should stay below 70°C under load. Program/Erase Cycle Count reveals how many write cycles the drive has performed. Uncorrectable Error Count should remain at zero.
5. Use manufacturer-specific tools. Download your SSD manufacturer's utility: Samsung Magician for Samsung drives, Intel SSD Toolbox for Intel drives, or SanDisk SSD Dashboard for SanDisk drives. These tools provide manufacturer-optimized health assessments, firmware updates, and performance optimization features specific to your drive model.
6. Check drive performance benchmarks. Run CrystalDiskMark or your manufacturer's benchmark tool to test read/write speeds. Compare results against your SSD's rated specifications. Significant performance drops below rated speeds may indicate health degradation or need for firmware updates. Test both sequential and random read/write performance.
7. Set up regular health monitoring. Schedule monthly health checks using your preferred monitoring tool. Enable automatic startup for health monitoring software and configure alert thresholds for temperature, wear level, and error counts. Document baseline health metrics when the drive is new for future comparison.
