Erasing SSD memory securely is much harder than it may appear
http://j.mp/h7R4vL (UCSD Non-Volatile Systems Lab)
"Our results show that naively applying techniques designed for
sanitizing hard drives on SSDs, such as overwriting and using
built-in secure erase commands is unreliable and sometimes
results in all the data remaining intact. Furthermore, our
results also show that sanitizing single files on an SSD is much
more difficult than on a traditional hard drive."

Lauren's comments:
With the rise of SSD memory as a replacement for traditional hard
disks, the security and privacy aspects of this situation seem quite
noteworthy, to say the least. You can bet that those parties (legit
or not) who wish to extract data from laptops, iPads, smartphones, or
other SSD-based devices will already be ahead of the curve. Ya' think
you really deleted that cleartext before sending out the encrypted
version? You sure you actually deleted that company confidential
material (or that porn!) before you head back through U.S. Customs?
