Spotlight on SD Card Industrial Grade Features
SD card design is governed by the Secure Digital Association. Although different companies manufacture them, every SD card on the market is designed to meet very specific guidelines set forth by the Secure Digital Association and shared with its members. As such, end users can rest assured that SD cards will always be compatible with their applications, even if they end up ordering cards from a different manufacturer in the future. SD card industrial grade features are designed to ensure that these memory cards can operate in industrial conditions in which temperatures, vibration, and shock are more intense than what’s usually encountered with consumer devices. Here is a closer look at some of the SD card industrial grade features you can expect.
SLC Flash
SD cards use NAND flash storage, and SD cards that are industrial grade use SLC NAND flash. SLC, or single-level cell, is the most reliable grade of NAND flash storage and is the form of storage most common in industrial devices. SLC is so reliable because only one bit of data is stored on each cell. This reduces the risk of many complications associated with flash storage, including cross-cell noise and data loss because of power failures during read and write operations.
Extended Operating Temperatures
Industrial grade SD cards are designed to tolerate extreme temperatures, as well as rapid temperature fluctuations. These memory cards can operate in -40 degrees C up to 85 degrees C without any loss of function or risk to the data on the memory card. This feature is essential for industrial grade applications, where memory may be stored in environments in which intense temperatures are normal.
Large Storage Capacities
SD card industrial grade features include the high storage capacities that are important to industrial users. Industrial SD cards have capacities ranging from 128MB to 32GB, so you can find the perfect fit for your application’s needs. To meet even larger storage needs, industrial grade SD cards with extended capacity can store up to 2TB.
SD cards are popular for industrial use because of their storage capacities, reliability, low power consumption, and easy device integration. Discuss your embedded storage needs with Delkin to see if an SD card is the right choice for you.
