In this Everything is Connected IoT
era, massive data generated from
many kinds of internet connected
devices. Which is also implying the
security risk of IT system is much
higher than before, even beyond
our imagination. For example, in
2016, a team of hackers managed
to take remote control of Tesla
and manipulate the devices inside
the car, even hit the brakes from
19 KM away. In 2017, a “white-hat
hacker” sent out 150,000 print jobs
in 24 hours which printed ASCII
art. All these “innovative” internet
attacks and the “creativities” from
the hackers are really the warnings
of our public safety, which could
be exposed to risks because of the
insufficient protection of IT devices.
Although these cases are more about
the safety of network connection and
communication protocols, but storage
medias in each layer of IoT structure
which carry data and remain system
operation, the reliability and security
is even more critical. In this article,
we will be discussing this topic from
storage hardware reliability, data
security, and application flexibility.
Great oaks from little
acorns grow, reliable SSD
is all about Flash
NAND Flash is widely adopted in IoT
applications as storage device, which
is the storage media that record
the data with proper arrangement
from storage controller IC. Hence,
the selection of IC defined most
of the reliability already. With the
incremental usage of Flash IC in all
kinds of the handheld devices and
3C products, the secondary market
of this kind of the storage IC also
emerged. All kinds of non-original
package IC, even second hand IC are
overwhelmed in the market already.
However, no matter data collection
or big data analysis in the cloud, the
whole eco-system of IoT applications
is about the value of data. If
emphasizing too much on cost and
apply Flash IC from secondary
market, which risks the reliability
of whole system and lowering the
expected value of data.
