TRIM Won’t Securely Erase SSDs

Some experts claim that SSDs which have TRIM enabled – most modern SSDs – don’t need to be securely erase because the process purges deleted data in the background. Unfortunately, you can’t count on TRIM to purge all your blocks even if you attempt to force it by using Windows 10 or 11’s Optimize Drive feature. I took the drive I’d wiped with Windows 10’s reset feature and then ran Optimize Drive on it, but my sensitive files were still recoverable with EaseUS Data Recovery.

This is an expected result from experience,” DriveSavers Director of Engineering Mike Cobb told us. “TRIM doesn’t always function with all devices. This is why TRIM cannot be trusted, ever unless validated with the system and the actual drive model.

DriveSavers is a leading data recovery service that uses its own set of proprietary tools to get deleted data off of clients’ SSDs and hard drives. For companies that are especially concerned about the quality of their secure erases, DriveSavers offers its “Data Erasure Verification Service,” where experts will check to make sure that nothing can be recovered.
