availability of SLC NANDrive|
Editor:- September 17, 2013 - One of
the pressures which has been driving embedded SSD designers towards the kind of
technologies which enable MLC to operate over the full
temperature operating range has been the
cost per terabyte
- but another has been the open question of whether it will be realistically
possible to guarantee sourcing SLC in the future at all - which is why some
companies like Virtium
have instead got product roadmaps which ensure that future design slots can be
filled with identical footprint SSDs which will use whatever future variations
of nand flash memory the future market is likely to offer.
contrast to the decades old market practise of stockpiling old technology
chips for use in legacy equipment designs which are assembled much later.
These longevity assurance programs can get complicated and expensive - and I've
even heard of recent cases where SSDs are emulating 1970s vintage
floppy drives to keep
some expensive machinery running.
There are risks involved in both
these approaches (to SSD design socket continuity).

For those in the
rugged and military SSD
markets - this type of consideration about long term product availability is
the usual way of doing business.
That's in stark contrast to the
enterprise SSD markets
- in which designers are more interested in the probability that they will be
able to get superior (faster and higher capacity) products in future
motherboard designs (so long as they are
software and interface
compatible) - rather than getting exact clones of the original devices to work
in the unchanged original motherboards.

The Disk on a Chip
product concept goes back
a long way...
In 1995 - EDN magazine
cited DiskOnChip as 1994's most innovative product for embedded systems. In
those days it provided 1 to 2 Mbytes of data storage.
Commenting on the
(1995) award - Dana
Gross, president of
M-Systems said - "DiskOnChip
represents the innovation and efficiency of M-Systems' technology. This
award-winning product has found applications in embedded computer systems, where
it provides a highly reliable solution for designs faced with space and power
SandForce joins LSI's new Flash Components Division
January 4, 2012 - LSI
it has completed the acquisition of SandForce.
comments:- most of the leading companies in the earth shaking
PCIe SSD market use
architecture controllers or software - which provides cost and efficiency
advantages when you compare usable capacities with maximun fault protection
That puts competitors who use small SSD architecture (such as
Seagate - who use
- and STEC which has yet
to establish a stronghold in this market with its own ASIC) at a potential
disadvantage as capacities scale up.
One of the design challenges for
LSI will be to see if they can extract the proven flash management features in
past SandForce controllers and scale them up to support bigger capacities and
faster throughput without adding latency penalties (which currently accrue with
arrays of SFPs) or which uses a new processor core or split controller
architecture to better support larger flash chip populations.
Viking ships nv 8GB DDR3 DIMM
Editor:- October 18,
Viking Modular Solutions
said it is shipping
extension of their nv module range.
ArxCis-NV plugs into standard
RAM sockets and provides
2GB to 8GB RAM which is backed up to SLC flash in the
event of a
power failure - while the memory power is held up by an optional external
25F supercap pack. Viking says these new memory modules can eliminate the need
for battery backup units in servers and the maintenance logistics associated
with maintaining them. They are specified as being maintenance free for "5
years @ 60C".
Editor's comments:- will these new modules
replace batteries in
RAM SSDs? - I doubt it
- because of scalability issues - like managing a spiderweb of 100+ dangly
bits of wire when you have a terabyte of RAM. Having said that - there are many
applications which only use a small number of memory chips which could benefit
from such a product.

Introduces World's Smallest Hard Drive
7, 2004 - Toshiba
today announced the development of a 0.85-inch hard disk drive, the first drive
to deliver multi-gigabyte storage in a
sub-one-inch form factor.
Expected to be available in 2GB and 4GB capacities, Toshiba will start sampling
the new drive in summer 2004, with mass production to begin in late 2004
Measuring only a quarter of the size of Toshiba's 1.8-inch drive, the 0.85-inch
HDD is expected to boost the functionality of a new generation of products,
including mobile phones, digital audio players, PDAs, digital still cameras,
camcorders and external storage devices.
Toshiba initially plans to
introduce capacities of 2GB and 4GB, and anticipates achievement of even higher
densities in the 0.85-inch form factor.
A prototype of the 0.85-inch
HDD will be shown at Toshiba's booth (#12214) on the CES show floor January
in January 2011 - over 30 manufacturers now market
drives in 1" and
smaller form factors - although for economic reasons these are mostly SSDs.
The history of this market is described in
