Exascend SD300 Industrial-Grade SD and MicroSD Cards Up to 256GB with 176-Layer 3D TLC NAND

Exascend, Inc. announces its SD300 series industrial-grade SD and microSD cards, designed to meet the storage demand of the IoT and edge applications.

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

Ruggedized for industrial environments and workloads
The SD300 series features proprietary hardware and firmware designs, allowing it to operate in a temperature range of -40°C to 85°C and resist shock, vibration, and humidity. With a MTTF of 2 million hours, the SD300 memory cards are built to handle significant workloads, incorporating technologies such as LDPC ECC, wear leveling, and pseudo SLC (specifically for 8 and 16GB cards) to deliver sustained performance, low storage latency, and endurance. Additionally, it comes equipped with a SMART tool that helps monitor card health status and ensure reliable operation.

Optimized to handle high-resolution images and 4K videos at the edge
The combination of 5G transmission speeds and AI computing has accelerated edge IoT deployment, leading to demand for smaller and higher-speed storage solutions. With sequential RW speeds of up to 90 and 80MB/s respectively, the SD300 offers performance that can meet the requirements of data-intensive applications. Both SD300 series SD and microSD cards carry speed class of V30/U3/C10 and performance class of A2, capable of supporting continuous 24/7 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 solutions that can meet the needs of their most demanding applications,” said Frank Chen, CEO. “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 for purchase from the company and its authorized distributors, with both models offering capacities from 8 to 256GB, and a 3-year warranty.
