Introduction

A European company well known for creating driving assistance hardware and software that informs users about nearby accidents, cameras, traffic jams, and police checks, as well as weather conditions, was facing reliability issues with the consumer-grade storage solution used in their smart device. Users of the company’s device complained that speed limit and road condition data was not reliable enough, and would sometimes present inaccuracies.

Challenges

Must be able to withstand excessive heat from prolonged exposure to sunlight
Must be able to operate during vibrations from the engine, and bumpy roads
Must be strong enough to withstand shock from sudden vehicle breaking
Read and write speeds must be stable to process critical data on time
Product materials should not change as they could impact functionality of the device
Sudden power loss from vehicle motor shutdown should not cause data loss
Keep failures to an absolute minimum to avoid damaging the user experience

Solutions

Operational temperature of -25° to 85°C
Can withstand vibrations of 20G @ 7-2000Hz
Can withstand shock of 1500G @ 0.5ms
The latest firmware architecture and flash algorithms, including superior wear leveling, and read disturb management ensuring high reliability and endurance
Fixed BOM guarantees product longevity and long-term supply
Abnormal power loss protection
MTBF (mean time between failures) of over 3 million hours

Result

Innodisk was able to help the client overcome their storage challenges by providing an industrial MicroSD card that met their unique reliability requirements. In doing so, the client was able to achieve a more stable data transmission, which improved the efficiency and accuracy of speed limit and road condition data reporting, as well as reduced maintenance costs.
