Completely erase an SSD?

A "Secure Erase" command was added to the SATA command set. You need to get a utility that will send it to the drive. Take a look here: https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase, or Google SSD SECURE ERASE.

Tom's Hardware uses this between passes of SSD testing to reset the drives to a completely unused state.

Thanks alot! I'm gonna check it out

Also, some vendors have their own toolbox / application (like Intel and OCZ) that have a Secure Erase feature built into the application. It is the easiest way to do so with those apps.

Also, HDDErase is another very well known / used application for a secure erase on a SSD or hard drive.
