CFast Cards

CFX740I


Transcend's CFX740I CFast card features 218-layer 3D NAND flash memory and a SATA III 6Gb/s interface, delivering high-speed data transfer, high capacity, a compact form factor, and plug-and-play convenience. The CFX740I incorporates SLC Mode technology, offering flash memory endurance of up to 100,000 program/erase (P/E) cycles to maintain consistent write performance. It supports a wide operating temperature range of -40°C to 85°C, making it suitable for outdoor equipment and harsh environments exposed to rapid temperature fluctuations. With exceptional endurance, it is specifically designed for write-intensive applications such as gaming machines, medical diagnostic equipment, transportation systems, and other embedded devices.
