Features
-
Containing no rotating or moving part as in hard disk drives , thus bes t suited fo r applicatio ns which require high
environmental resistance (to temperature, humidity, vibration, shock) and for continuous operation for extended
periods of time.
-
Never making any sound such as motor rotation sound or access noise during seeking, thus best suited for
applications which require complete silence.
-
Lower in power consumption than hard disk drives
-
The product comes with a protective function that minimizes disk failures during an instan tan eou s stop. *1
*1 This function is not designed to protect files (or data) written onto the disk.

About write endurance
PC-ESD series have a write endurance which limits the number of times each memory may be written,
due to the characteristic of the memory that is used. A write endurance can be calculated by the
following formula as a reference value:
