April 29, 2016 - Usually the last thing you want to see as an SSD designer is
your hot new product going up in smoke - but autonomous self destruct of SSD
data takes many forms and this is one of them. |

shows a verification test rig for this functionality. Renice says it
uses a specially designed electric circuit, which ensures that all NAND flash
chips in the SSD will be burned through.
Editor's comments:- I've asked Renice if they've analyzed the
composition of the smoke - but this kind of
fast purge is aimed
applications rather than civilian offices - so smoke fumes are the lesser of
two evils (compared to data capture by a foe). I've asked Renice to say how much
electrical energy is needed to complete the data burn and will post an update
here when I know. ...watch

February 2015 - "Remotely
triggered data destruction isn't a new idea in secure SSDs - but it hasn't
really taken hold in the past due to the disruptive effect of false positives.
For those reasons Waitan's StellaHunter is triggered by 2 or more preset
conditions. Users can also choose whether the SSD should be reusable after the
secure erase or whether the SSD should have a destructive erase."

2011 - "Foremay 's presentation discusses different approaches for
the secure erase of data on SSD's. Although key destruction of a self-encrypting
drive provides some protection and is very fast, the data remains on the drive
leaving the possibility of decryption with breakthroughs in the future. Secure
erase eliminates this possibility entirely, and can be done with a
hardware-based, one-key self-destroy disk purge in a few seconds, or a secure
erase using a one-key or software-based method in several seconds. These options
provide a range of methods to keep the data secure."

May 2002 - "Securing
confidential data is essential: as the damage that can be caused when it falls
into the "wrong hands" is devastating... Deleting files from a
mechanical disk does not actually erase the data as only the File Allocation
Table (FAT) is being updated but the data still resides within the disk. Some
SSD designs enable users to erase the entire disk in typically 5 seconds."
||Megabyte knew how to destroy data
If you're seriously interested in data security in SSDs you'll already know
that encryption is simply a promise to delay access to secured data rather than
a guarantee that it will remain denied to those who shouldn't see it.

parts of the SSD market such as where SSDs designed for one market can be
redeployed into another (for example when
technology drives are placed in enterprise flash arrays by companies like
Pure and wrapped
around by enough
software to enable
their safe use for enterprise use) you'd think that the determination of what is
a military SSD should be quick and relatively unambiguous.
So when we
ask the next question - what is a military SSD company? - That should
be even easier to decide.
I've long believed it would be useful to
compile and publish a simple frills-free list of military SSD companies which
readers could use a guide for their own follow-up research.
