All our modules undergo rigorous laboratory testing to ensure they provide the highest performance and reliability. The ISO 9001 certification of design and manufacturing procedures assures you that Transcend's memory exceeds the industry standards for quality. Our memory is subjected to rigorous testing at every stage if development. Post manufacture testing includes a severe 72 hour dynamic burn-in testing to identify flawed components before shipment, as well as real machine testing to prove their dependability in an actual working environment.
