Wipe the encryption key of your SSD, small amount of data to wipe, and the whole SSD is unrecoverable. FWIW at least OCZ SSDs have an encryption key flashed into it even if you didn't turn encryption on. Putting a new firmware on it can wipe this key and make your old data inaccessible. Source: got a buggy OCZ firmware that failed to make the device appear on the SATA bus, only way OCZ could fix it was to install new firmware which wiped the key and hence my data was unrecoverable.

Interesting point. I stand corrected. Not sure why I didn't think that way.
