Utility SD / microSD

Delkin Devices developed the Utility concept for OEM’s and embedded designers that need a cost-effective, yet controlled storage solution. In many cases, the cost of the host and the usage model does not support the use of high-endurance SLC flash, yet the application still requires an industrial-grade product, consistent performance and life cycle management.
