The headends is shipped with a Transcend SDHC 4GB Class 4 SD Card. This SD card contains built-in ECC (Error Correction Code) that automatically detects and corrects errors during data transfer, and also utilizes a sophisticated wear-leveling algorithm for consistent long-life operation.
It has the same write cycles as other cards. The difference between highend card and midrange card, is normally Read/Write speeds and temperature ranges. The headend has no need for "high speed" card and the temperature range is within the needed range.
