Transcends Industrial CF cards are specially designed to meet the strict demands of high-end equipment & machines that run at extreme temperatures. The operating temperature range of Industrial CF cards is much better than normal CF cards, with full functionality down to -40 degrees C & as hot as 85 degrees C (normal CF Cards are only rated at -25 degrees C to 85 degrees C). Aside from their excellent temperature flexibility, these cards are exceptionally resistant to shock, vibration & dust, while consuming less power & maintaining ultra fast data transfer speeds. Their superb compatibility & durability makes them suitable for use in standard PCMCIA-ATA equipped devices such as industrial PCs, embedded systems, medical instruments, factory automation systems, network infrastructures & other industrial equipment. In addition, Industrial CF cards can even be used as bootable disks in place of conventional hard drives that cannot withstand the harsh conditions of an industrial environment. Transcend uses SLC (Single-Level-Cell) NAND Flash chips in its industrial CF cards to assure the highest level of quality, durability, & long-lasting data retention. The Ultra Speed card supports Ultra-DMA modes 0-4 & dual channel operation to ensure maximum compatibility at the highest speeds possible. Transcends Industrial CF cards achieve extraordinary average read/write speeds of up to 42MB/30MB per second while maintaining industrial-grade stability. With its built-in Error Correction Code (ECC) to ensure data accuracy, resistance to severe conditions & superb transfer performance, the Ultra Speed Industrial CF card clearly lives up to its name.
