|SSD Encryption Everywhere?|
August 25, 2014 - the future of SSDs is "self-encryption everywhere!"
the conclusion of a paper -
with Self Encryption: Solidly Secure (pdf) - which was presented recently
at the Flash Memory Summit.
author Michael Willett
(who has worked as a storage security strategist for various leading
organizations) reviews the threats and business impacts posed by data security
breaches, and compares the performance of HDDs and SSDs both with and without
Editor's comments:- while I'd agree that security
inside storage devices is nearly always a good thing - I can think of some
examples in which the opposite is true.
For example:- when scientists
are using SSDs as data loggers which collect raw physical data - particularly
in experiments where due to environmental conditions there is a possibility
that the drives may fail during the experiments.
Drives which are
encrypted pose challenges for
disabling encryption - or not having it in the first place - may be a good thing
for this type of application.
The biggest risk posed by losing the
drive in a phsyics experiment - or astronomical observation - is that one of
your colleagues extracts the data before you - but you'd know that by reading
On the other hand if the drive fails - and it's still in
your possession - then you can recover the data for yourself - you may change
your career prospects by having captured the details of a rare event.
Cactus adds write disable switch to industrial CFast

that it has introduced a new security option - of having a physical
write protect switch - in its
series of industrial SLC CFast SSDs.
It works like this. When
the write protect switch is in the disabled position, the CFast card reads and
writes as normal. When the switch is enabled, the card will read as normal, but
all write attempts are ignored. Data already stored on the card is safe from
"This write protect feature has already been
successfully implemented in the gaming, military and other markets" said
Ng, President of Cactus Technologies.

Microsemi's new SSD for vetronics can erase 256GB in < 8S
May 23, 2013 -
announced that it has
secured multiple design-wins for its new Series 200 TRRUST-Stor (rugged self
encrypting, 2.5" SATA SSD with 256GB SLC capacity and
company says a full hardware-based erase takes less than 8 seconds. The 200
model has R/W throughput which is twice as fast as the company's earlier
TRRUST-Stor due to a new generation of the company's Armor processor.
Developed to endure harsh environments the new SSD - which has
hardware-implemented AES 256 encryption - can withstand up to 3,000G shock and
30G rms of vibration.

SSDs or hard drives? - the data forensics differences
October 23, 2012 - When you need to retrieve critical unbacked up data from a
damaged notebook (which you left in the car when you clambered out the
window after realizing that the puddle across the road was much deeper than you
first thought) you call the process "data recovery" - but
when a court seizes a suspect's notebook to try and retrieve data which may have
been deliberately "deleted" - they call it "data forensics"
- either way - in the most demanding cases the experts who work on these tasks
are the same.
SSD Data Recovery
(as opposed to dumb flash memory recovery) is a relatively new market which
didn't exist 5 years ago.
A recent article
SSD Drives Destroy Court Evidence - on a site called
ForensicFocus.com - discusses how
techniques which are essential to the operation of flash SSDs (such as
and wear leveling)
mean that from the forensic viewpoint SSDs yield up potentially much less
deliberately deleted recoverable data than hard drives.
RunCore's video - phone to purge USB SSD
May 22, 2012 - sometimes if I'm watching a movie I realize it's going to be
bad - but in a way which is nevertheless all too fascinating to watch. How bad
it will get? Look! - see it's getting worse - but still taking itself
seriously. So - instead of zapping it like I should - I stay transfixed.
Such bad movies are an artform.
What about promotional videos though?
- on the subject of SSDs...
Mostly these are just time wasting. But
today - in the "so dreadful I kept watching it nearly to the end"
category was a

chasm which divides military
SSDs over to the
consumer SSD market
- which it did 2
years ago - and the new video is simply about their latest model which
combines RFID with the phone zap technology in an external USB connected SSD.
As a security
concept I was convinced the idea had merit - when I first wrote about it 2
years ago. So I wasn't keen to see another new video about the same topic. But
I'm glad I did - because it's an artform. ...click to

RunCore launches world's 1st CF card SSD with fast purge
November 9, 2010 -
RunCore has launched
the world's first CF card compatible SSDs with fast (typically 30 seconds)
The fast erase - which is designed to protect confidential
data leaks and thwart any attempts at
data recovery - is
achieved by pressing a button or activating erase pins while the device is
powered. It can be once again used by formatting after the data destruction
Editor's comments:- due to the popularity of the CF
form factor in consumer products many equipment designers have adopted it as a
convenient way of incorporating solid state storage into products in the
industrial, medical and prosumer markets. Without an on-board fast purge feature
- achieving effective
as a software process in an SSD can take upto 24 hours (depending on disk
capacity). RunCore's industrial CF cards are true SSDs with wear-leveling,
vibration tolerance and low power consumption.

ZoneLoc Prevents flash SSD Data Walking into the Wrong Hands
Phoenix, Arizona - February
12, 2009 - White Electronic Designs Corp announced a new technology -
ZoneLoc - which automatically desanitizes a flash SSD to military standards
- when the device is moved outside a specified operating zone - to prevent data
falling into enemy hands.
The boundary can be tied to a fixed
location or made to be portable for mobile applications. ZoneLoc has
configurable features and options, including audible warnings, programmable
response times, wireless remote purging and sensitivity modes. Because the
protected device takes its own action, autonomously, security is guaranteed.
