Removable Storage Solutions for Industrial
and IoT Applications at the Endpoint to the Edge
The Industrial and IoT storage markets are changing rapidly due to applications and devices with increased compute power, edge computing,and advanced capabilities such as Artificial Intelligence (AI) and machine
vision. These advancements, along with an increase in the number ofconnected devices and sensors, are driving a need for higher capacity
and higher reliability storage solutions. Western Digital’s Edge storage
devices like the Industrial grade microSD cards capture data locally as
primary or backup storage and can help maximize network efficiency
and enable systems to analyze data and act on results in real-time.
Western Digital’s microSD cards can also be used with an adapter to fit
SD form factors, making these cards a flexible and scalable removablestorage solution.
Leveraging 30 years of expertise in NAND flash memory and storage
systems, Western Digital Industrial grade microSD cards deliver edgestorage solutions for Industrial and IoT applications requiring highreliability, durability, and high-intensity recording across a wide range of
operational requirements. Designed and tested to withstand the mostdemanding conditions and featuring an advanced memory management
firmware (FW), which includes power immunity, auto/manual readrefresh, ECC, and wear leveling, data-intensive applications can rely on
Western Digital Industrial products to capture every critical moment,
log each event, and to ensure quality of service to end-users. Thesehigh endurance solutions offer extended product life cycles which canreduce total cost of ownership (TCO) per system by eliminating costly
redesigns and requalifications while minimizing unnecessary maintenance calls.
Western Digital Industrial grade microSD cards are specifically designed
to meet the endurance, security, performance needs and environmental
requirements for a wide range of Industrial and IoT applications including
drones, action cameras, home surveillance, gateways, servers, and more.
