The Secure Digital (SD) card is a proprietary type of non-volatile flash memory. Originally introduced in 1999, the SD card was intended to replace MultiMediaCards (MMC). Since then, its versatility and portability has made it the flash memory device of choice for use in portable devices, including cameras and smartphones. OEMs who are looking for the best industrial SD card for their particular applications will first want to make sure they are selecting an industrial card, rather than a consumer grade card. A consumer grade SD card will typically use multi-level cell (MLC) flash, whereas an industrial SD card will typically use single-level cell (SLC) flash.

Industrial SD cards can withstand environmental extremes.

The best industrial SD card is designed to hold up to extreme conditions. Whereas a consumer grade SD card may only need to power a videogame player or a personal camera, an industrial grade SD card might need to withstand extremes in temperature in industries such as aerospace, transportation, and manufacturing. At Delkin, our industrial SD card is designed to operate perfectly in temperatures ranging from as low as negative 40 degrees Celsius to as high as 85 degrees Celsius. They are also resilient enough to withstand other environmental variables, such as shock and vibration.

Industrial SD cards are available in a range of capacities.

OEMs prefer to select the best flash storage for their application requirements. In some cases, this may mean choosing an industrial SD card with a low capacity, such as 128 MB. However, other applications may require a much higher storage capacity, which is why Delkin’s industrial SD card is available with a capacity of up to 32 GB.

Industrial SD cards offer additional features for greater functionality.

Capacity and resiliency are not the only factors to consider when selecting an industrial SD card for any given application. OEMs should also consider looking for additional features that add greater function to the flash memory device. Wear leveling, for example, will ensure that the memory cells are used efficiently. A locked bill of materials (BOM) is also an ideal feature, as it ensures long-term compatibility.
