High Capacity Removable Storage Solutions
for Industrial and IoT Applications at
Endpoints and the Edge
The Industrial and IoT storage markets are changing rapidly due to appli-
cations 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 of connected
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 SD cards capture data locally as primary or backup
storage and can also help maximize network efficiency and enable systems
to analyze data and act on results in real-time.
Leveraging 30 years of expertise in NAND flash memory and storage systems,
Western Digital Industrial grade SD cards deliver edge storage solutions
for Industrial and IoT applications requiring high reliability, durability, and
high-intensity recording across a wide range of operational requirements.
Designed and tested to withstand the most demanding conditions and
featuring mechanical switch write-protection and an advanced memory
management firmware (FW), which includes power immunity, auto/manual
read refresh, 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. These high
endurance solutions offer extended product life cycles which can reduce
total cost of ownership (TCO) per system by eliminating costly redesigns
and requalification while minimizing unnecessary maintenance calls.
Western Digital Industrial grade SD cards are specifically designed to meet
the endurance, security, performance needs and environmental require-
ments for a wide range of Industrial and IoT applications including industrial
PCs, printers, GPS navigation, gaming consoles, and more.
