Secure erase is the best way to securely and completely wipe all traces of data from your solid state drive.
Block wiping programs like DBAN are not only tough on the disk, but they are also limited in effectiveness. This is because on an SSD, the SSD's controller is responsible for directing where data are written. The DBAN program does not have that control, thus it cannot erase every trace of data. With that said, a bootable program like DBAN is much more effective than a windows based wiping program that wipes over the free disk space. These programs often miss data hidden in the MFT.
The secure erase command fires a voltage spike through the SSD and clears the NAND of all stored electrons. The data is irrecoverable, and the SSD is reset to factory speeds. It is safe, fast, and extremely effective. There will be absolutely no trace of data remaining. I recommend using
Parted Magic to secure erase your drive. To use this program, you will need to burn a copy of the .iso file on to a CD using a program like
ISO recorder.
Once you've got the program, you'll need to boot your computer from the CD-ROM. Then you can start the wiping process.
Here is a good video tutorial on how to use Parted Magic:
This is a very good article talking about secure erase and the benefits over block wiping (i.e. DBAN):
