The Delkin SD 600X memory card is designed to excel in DSLR cameras and advanced camcorders that require faster speeds and performance. With capabilities to write data at speeds over 45MB/s, the SD 600X series supports HD and 3D video recording as well as rapid-fire RAW photography in DSLRs. Unlike memory cards that are mass designed and built, the Delkin SD 600X card is manufactured with carefully chosen and controlled components to increase compatibility, longevity, reliability and overall quality. Proudly designed and engineered in San Diego, CA and supported by our Lifetime Warranty. Note: The 128GB SDXC 600X UHS-I Memory Card will only work with SDXC compatible cameras.
