Comparing Industrial and Utility Cards
When choosing embedded flash memory for an application, the grade of the card is one of the most significant factors. Industrial and utility cards are used in both commercial and industrial operations, but they have different features. As such, when deciding between industrial and utility cards, it’s important to consider the features that are most important to the design of your application and how it will be used. Delkin makes both industrial and utility products, and our team can help you make the right selection. Here is a look at how these two types of cards compare.
Type of Flash Technology
Industrial cards use SLC flash. SLC stands for single-level cell, and it refers to the amount of data that is stored on each cell in the memory card. With SLC flash, there is one bit of data stored on each cell. The benefit of SLC flash is that storing one bit of data per cell allows for the maximum possible processing speeds and extends the life of the card, because fewer voltages are used to store single bits.
MLC flash is used in utility grade products. MLC stands for multi-level cell. With this kind of flash, two bits of data are stored per cell. This increase in data storage on each cell means that processing times are slower than with SLC and that the cards wear out faster. However, MLC is used widely in commercial products and is the appropriate choice for many applications.
Operating temperature is a big driver behind industrial grade storage products. Many industrial applications are exposed to extreme temperatures and significant temperature fluctuations. As such, industrial grade cards are designed to work in temperatures ranging from -40 degrees C to 85 degrees C.
Utility products have slightly more limited temperature ranges. These products can be used in temperatures from -25 degrees C to 85 degrees C. However, there is another level of utility card called utility+. Utility+ cards have the same operating temperature range as industrial products.
For both industrial and utility cards, there are a variety of storage capacity options. Because utility cards use MLC flash technology, they are available with greater storage capacities, since they can store more data in the same amount of space.
There are many different factors to consider when it comes to choosing between industrial and utility cards. Delkin’s product team is available to help you evaluate the options and find the best fit for your needs. Contact us today for more information.
