Back up any data you want to keep
Check whether the SSD is the system drive or a secondary drive
Use the manufacturer’s secure erase tool if available
Use BIOS, UEFI, or the drive utility to run Secure Erase or Sanitize
If using Windows, use DiskPart to clean the drive
If using Linux, use hdparm or nvme-cli secure erase or format commands
If using macOS, use Disk Utility erase options if supported
Remove all partitions and format the SSD after wiping if you plan to reuse it
Verify the wipe by checking that the drive shows as unallocated or empty
Reinstall the operating system if the SSD was the boot drive
Physically destroy the SSD only if it must never be recovered
