FAQs about Flash Storage Devices
Flash storage devices are a key component in many commercial and industrial applications. There are multiple flash storage devices available for easy integration into a wide range of product designs. Questions often arise as engineers consider flash storage device options. Here are answers to some of the most common queries.
What exactly is flash storage?
Flash storage devices are an alternative to hard drives for storing data. With flash storage devices, data is stored in memory cells. Flash memory has very fast read and write capabilities, so it offers better performance than hard drives. Flash memory is also more durable than other options, since there are no moving parts that can malfunction. In addition, it requires less power than hard drives, so it can help to reduce energy costs for users.
What is the difference between SLC and MLC flash?
Two major categories of flash storage devices are SLC and MLC. Both of these refer to the cells used to store data. SLC stands for single-level cell, and it refers to flash memory in which one bit of data is stored on one cell. MLC stands for multi-level flash. With MLC, two bits of data are written per cell.
SLC flash is usually used in industrial applications, while MLC flash is most often used in commercial devices. There are many reasons for these distinctions, including the importance of data protection, the need for processing speed, and the cost of flash storage. Another kind of flash, TLC—triple-level cell—allows three bits of data to be stored per cell. TLC is used almost exclusively in consumer products.
When should industrial flash storage devices be used?
Industrial flash storage devices are typically used in applications that operate in rugged environments. This includes environments with extreme temperature fluctuations or high temperatures, as well as environments with exposure to shock or vibration. Devices that manage critical data also typically use industrial-grade flash memory devices. Healthcare, embedded computing, digital signage, and transportation are just some of the industries in which industrial-grade flash storage devices are used.
