new memories, new questions about data security
August 4, 2016 - the need to manage data risk when recycling hard drives,
SSDs and other storage devices is well known. But what about so called "volatile
memory" like DRAM?
We've become accustomed to seeing crossover
architecture concepts between storage and memory as the market progresses
complex memory systems and enterprise storage.
questions arise when virtual RAM becomes implemented by memories such as
flash and other alternative
nvms. And what about DRAM itself?
It was those thoughts which led

more about the security features
SED uses random AES encryption keys that are generated at product initialization
(leveraging the drive controller's integrated random number generator), which
are hashed and then stored within the drive itself. They are used in conjunction
with the integrated AES encryption engine to encrypt and store the host data on
the NAND flash without burdening the host system.
The encryption keys
are non-retrievable and cannot be changed without the complete loss of the data
on the SSD. Virtium's new StorFly SEDs are Trusted Computing Group Opal

fast. Takes only a second to complete the crypto erase of a Foremay SED SSD with
capacity of up to 20TB.
This erase can be triggered by a command or a user presettable
threshold of failed access attempts.
Commenting on the benefits of
intrinsic hardware encryption instead of relying on software and aside from
the obvious performance - Foremay says hardware encryption is far more secure
because software can be corrupted...
"Information security on
SSD drives has become increasingly important to all users, particularly in
government, defense, financial and medical industries," said Jack Winters, Foremay's
CTO and cofounder.
Editor's comments:- The effect - I guess -
is a bit like the accidental predicament of needing
data recovery for
a damaged and unsupported encrypted SSD. But a deliberate erase like this

SSD Encryption Everywhere?

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

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.
