Solid State Drive
Introduction A reliable means of data storage is a concern in industrial applications
with harsh requirements. Standard rotating media with its spinning
platters and head arms (with temperature limitations) present
obstacles to the reliable storage of data.
Solid state drives (SSD) are a direct replacement for rotating hard
drives on the IDE bus. They are drop-in replacements for their hard
drive counterparts.
Solid state drives offer improvements over the standard hard drive.
•
Improved thermal performance
•
Higher levels of shock/vibration
•
Less power required
•
Longer data retention
•
No moving parts
The rotating hard drive is susceptible to shock and vibration. This
weakness becomes more apparent as the temperature increases.
Although the solid state drive offer improvements in these areas, you
must consider limitations of other key components within your
systems before choosing to replace hard drives.
The decrease in the cost per megabyte of memory in flash drives is
making the solid state drive a viable alternative, especially in harsh
industrial environments.
Installation Use caution when installing or handling a solid state drive. Even
though the solid state drive is typically designed with a case around
the PCB assembly, you must handle the drive with care to prevent
possible electrostatic discharge (ESD) damage.
Follow these guidelines when installing or handling a solid state drive.
•
Do not touch the exposed connector; handle by the case.
•
Ground yourself whenever possible before handling the solid
state drive.
•
Leave the product in its protective ESD bag until the time of
installation.
