Importance of Power-Loss Data Protection
During a “clean” shutdown, most host sytems initiate
a command (the STANDBY IMMEDIATE command) to
an SSD to give the SSD enough time to prepare for
the shutdown. This allows the SSD to save data
currently in transition (in temporary buffers) to the
non-volatile NAND media.
However, during an unsafe power shutdown, the SSD
abruptly loses power before the host system can
initiate the STANDBY IMMEDIATE command. This
prevents data in the temporary buffers from being
saved in the non-volatile NAND.
In the Intel SSD 320 Series, user data and system
data are stored in temporary buffers for a very short
period of time compared to their residency in the
NAND media. The Intel SSD 320 Series makes sure
both types of data are protected during unexpected
power loss events.

How Power-Loss Data Protection is
Implemented
Implemented
The Intel SSD 320 Series contains hardware- and
firmware-based power-loss data protection features.
The SSD includes a power-fail detection circuit, which
sends a signal to the ASIC controller in the SSD
indicating there is an imminent drop in power level.
Triggered by this, SSD firmware disconnects the
input power from the SSD.

The SSD then relies on its on-board power-loss
protection capacitance to provide enough energy for
the SSD firmware to move data from the transfer
buffer and other temporary buffers to the NAND.

What Type of Data is Protected
During an unsafe shutdown, firmware routines in the
Intel SSD 320 Series respond to power loss interrupt
and make sure both user data and system data in the
temporary buffers are transferred to the NAND media.
Additionally, given the energy provided by the
capacitor elements and urgency to recover data,
firmware de-prioritizes non essential controller
activities to quickly get into data saving mode

Power-loss Tolerant Storage Capacitance
The heart of the Intel SSD 320 Series power-loss
protection scheme is the on-board power-loss tolerant
storage capacitance.
The Intel SSD 320 Series uses small value, light-weight
discrete capacitances to assure that all user data is
saved to the storage media. This solution is different
from a super capacitance-based solution. The
capacitors are rated to meet Intel SSD operational
specifications. This ensures that sufficient energy is
stored at any given time during different operating
conditions as well as throughout the life of the SSD.
