Exascend Industrial Cfast CFS300 SATA III 256GB

The Exascend EXSD3X256GB-I is a 256GB CFast 2.0 card, delivering sustained read speeds up to 520 MB/s and write speeds up to 300 MB/s with 3D TLC NAND flash for high-reliability enterprise applications. Featuring SATA interface, 3.3 V operation, and extreme temperature tolerance (-40C to +85C), ideal for extreme workloads in industrial, surveillance, or embedded systems.

The Exascend SI3 series EXSD3X256GB-I CFast 2.0 memory card is a high-performance, ultra-reliable storage solution for enterprise-grade applications demanding sustained high-throughput data handling, such as video surveillance, machine vision, and industrial automation. Leveraging advanced 3D TLC NAND flash technology managed by a single-chip controller via SATA III interface (up to 6 Gb/s), it achieves sequential read speeds of 520 MB/s and write speeds of 300 MB/s, alongside 85,000 IOPS for 4K random read and 70,000 IOPS for full-drive 4K random write, eliminating the mechanical vulnerabilities of HDDs like platters or motors for enhanced MTBF and reduced failure rates. Its solid-state architecture ensures low power draw (3.3 V operating voltage, <2 W active), compact form factor (42.8 x 36.4 x 3.6 mm, reel packaging for bulk), and resilience in harsh environments, operating from -40C to +85C with shock/vibration tolerance up to 1,500 G/20 G.
