SD Smart Tool Primer

Can your SD or µSD card tell you how much life it has left?

SD Card S.M.A.R.T. Primer

Envoy Data Memory SD and µSD controllers implement CMD56 support and specialized firmware to provide S.M.A.R.T. like features to systems designers. One of the biggest concerns that system designers have with NAND Flash based storage and mobile, remotely deployed hardware systems is replacing worn out SD Cards or µSD Cards. Or worse, not knowing IF the SD Card or µSD Card even needs to be replaced based on endurance estimates.

The use case for all Solid State Storage has a significant impact on the life of the product. If system designers implement Envoy Data Memory SD Cards or µSD Cards they can monitor card life as part of the systems background tasks. Hardware that is connected can notify users or administrators in the event that the card begins to reach an END OF LIFE condition.

Envoy Data Memory supports this feature with a S.M.A.R.T. tool available to our customers seeking smart SD card solutions they can count on the last and perform.
