Taiwanese flash storage company Exascend has announced its SD300 industrial-grade SD and MicroSD cards to meet growing IoT edge application demand.

Built with 176-layer 3D TLC NAND technology and ruggedised for harsh environments, the compact and removable storage products are for edge IoT applications such as gateways, industrial drones, factory robots, surveillance cameras and infotainment systems.

They feature proprietary hardware and firmware designs, allowing them to operate from -40 to +85˚C and resist shock, vibration and humidity. With a mean time to failure of two million hours, the memory cards are built to handle significant workloads, incorporating technologies such as LDPC ECC, wear levelling and pseudo SLC – specifically for 8 and 16Gbyte cards – to deliver sustained performance, low storage latency and high endurance.

Additionally, they come with a smart (self-monitoring, analysis and reporting technology) tool that helps monitor card health status and ensure reliable operation.

The combination of 5G transmission speeds and artificial intelligence (AI) computing has accelerated edge IoT deployment, leading to demand for smaller and higher-speed storage. With sequential read and write speeds of up to 90Mbyte/s and 80Mbyte/s, respectively, the SD300 can meet the requirements of data-intensive applications.

Both SD and MicroSD cards carry speed class of V30, U3 and C10 and performance class of A2, capable of supporting continuous round-the-clock video recording and processing high-resolution images and 4K footage at the edge.

“Exascend is committed to providing our customers with the highest-quality storage that can meet the needs of their most demanding applications,” said Frank Chen, CEO of Exascend. “The SD300 series industrial memory cards are the latest additions to our portfolio, and we are confident that they will be valuable for our customers in the industrial sector.”

The SD300 series is available now for purchase from the company and its authorised distributors, with both models offering capacities from 8 to 256Gbyte, and a three-year warranty.
