How to Wipe an SSD

by Ezekiel James

A common misconception among average computer users is that deleting files from your solid state drive (SSD) is the same as wiping the data. This is because when files and folders are erased, there appears to be more disk space on your drive. The problem is that merely erasing data doesn't remove it completely. According to, an erased file is not completely removed from your SSD until the file is replaced with new data. Fortunately, there are several tried and true methods for successfully wiping an SSD.
