Building on what LogicX said... SSDs have a translation layer that converts the logical read/writes to the physical flash storage. So, low-level writes (from the OS's perspective) won't necessarily line up with what is physically written. I think that in theory if you wrote 5-10X the size of the drive, you might be able to write zeros to each of the flash pages, but I don't think you'd be able to confirm that.
