CFast Cards

CFX735 & CFX735I


Transcend's CFX735 CFast card is designed with 112-layer 3D NAND flash and SATA III 6Gb/s interface, featuring high transfer speeds and large capacities, as well as plug-and-play convenience.  The CFX735 can operate stably under -5°C ~ 70°C, and wide-temperature(-40°C ~ 85°C) model can be provided upon request. The CFX735 comes with SLC Mode technology, enhancing flash endurance to 100K P/E cycles while having a sustained write speed that is suitable for write-intensive equipment. Otherwise, the CFX735 includes an Write-Protect Switch—a simple yet powerful tool that instantly safeguards your data. With one quick switch, lock your files from accidental edits, deletions, or unauthorized changes.
