Re: I need to wipe an SSD What you want is called Secure Erase -- no it's not a program, it's an ATA protocol command that resets the FTL and zeros NAND pages. After that the drive will behave/perform exactly like it did out-of-the-box when you bought it. Secure Erasing doesn't take very long, so don't be surprised if it's done in under a minute.
One free GUI-based utility which lets you issue the Secure Erase ATA CDB is called Parted Magic. Burn the ISO to a CD and boot it. Then follow this method:
You will need to have the SSD hooked up to a native SATA port on your motherboard for this to work reliably. Please do not waste time with enclosures/USB-SATA bridges or other nonsense -- just do it right from the get-go.
If you have issues with the GUI and have an nVidia card, you may need to choose the Alternate graphical server item from the main menu. If that doesn't suffice (e.g. it worked for me but the text was completely unreadable), you may need to try Failsafe Menu -> KILL Nouveau.
If the download sites are too slow (most of them were for me), try getting it via their torrent, or any tracker of your choice. Filename is pmagic_2012_11_30.iso.
You may also want to use this opportunity to update the SSD firmware. Bare minimum make sure you're running something newer than this or else you may risk the person you sell the SSD to holding you responsible for issues.
