Solid State Drives (SSD) use different media and storage technologies than conventional Hard Disk Drives. Since SSD uses compression and over-provisioning to increase device performance and lifetime, a single overwriting pass is not enough to clean a whole storage and traditional schemes may not guarantee the desired result.
Before selecting the wiping scheme to use for the wiping process, you should take into account the following factors:
- Due to SSD's internal compression, only random passes can be effective on some drives
- By featuring reserved area (typically 7-20%), a single wiping pass has no chance to overwrite the entire SSD; 2 passes minimum are required
- Frequent or massive SSD overwrites reduce the drive lifetime
To achieve the best wiping results on SSD with BCWipe Total WipeOut use the 3-pass DoE wiping scheme and enable 'Replace the last wiping pass by ATA ERASE command' (last step in Wizard for BCWipe Total WipeOut).
While the first two passes overwrite the drive with minimal impact on lifetime, the last pass runs the ATA SECURITY ERASE hardware sanitization command followed by TRIM for the entire device (if supported by the drive).
We recommend to use the latest SSD firmware offered by drive vendors. According to a study conducted by the University of California, San Diego, some SSD firmware failed to implement ATA SECURITY ERASE correctly.
