Compact Flash cards have been designed for uses in the industrial temperature range and comprise features, such as extended wear levelling, bad block management or AutoRefresh to ensure a high data quality. The PowerProtector feature provides additionally a comprehensive protection against power failures. Compact Flash cards are based on the PATA interface and are still very popular among industrial users because of their reliability and robustness. They are particularly suitable for applications with a high data throughput, such as HD video recordings in surveillance cameras.
