TECHNICAL NOTES The Advantages of BrightSign SDHC Cards BrightSign, LLC. 16795 Lark Ave., Suite 200 Los Gatos, CA 9503 408-852-9263 | www.brightsign.
INTRODUCTION BrightSign players are fully compatible with all SD cards. However, we recommend using BrightSign SDHC cards to improve the long-term reliability of looping-video presentations and reduce the chance of read errors. Summary When you use a BrightSign player, your content and playlists are loaded onto an SD or SDHC flash card. Although all SD/SDHC cards rely on a standardized interface, there are large differences in performance and reliability among various card brands and models.
MLC and TLC BrightSign SDHC cards use a type of NAND flash technology that is less susceptible to read errors than many other card brands. Many SD card manufacturers use “triple-level” (TLC) flash chips, which are more vulnerable to read issues than the “multi-level” (MLC) flash chips that BrightSign SDHC cards use. MLC flash chips provide faster write performance and greater reliability.
