Choosing the Right Storage Solution for Embedded Applications
Any embedded system needs reliable access to storage. This may be provided by a hard disk drive or access to a remote storage device. Alternatively there are many flash solutions available on the market today. When considering flash, there are a number of important criteria to consider with capacity, cost, a...nd reliability being foremost. This paper considers hardware, software, and other considerations in choosing a storage solution.
Wear leveling is an important factor affecting the expected lifetime of any flash solution, and it can be implemented in a number of ways. Depending on the choices made, software changes may be necessary. Solid state drives offer the most straight forward replacement option for Hard disk drives, but may not be cost-effective for some applications.
