Before discarding the SSD, try doing a secerase using /sbin/atactl. This may make the drive usable again. Whether it will be reliable or not is another question, but the results of a secerase might be interesting or useful for other users in a similar situation searching the list archives. By default the drive will be freeze locked against doing a secerase, because the kernel issues the freeze lock command during device initialsation and likely your bios does too. There are various ways around this, the easiest is probably to suspend and then resume the machine if this is supported by your hardware, because then the drive will, (hopefully), be power cycled and the kernel doesn't re-issue the freeze lock command on resume, (which is probably a bug in itself).
