General Features TOUGH Specification Cards SF-G series TOUGH specification cards are designed for dependability. The one-piece molding body with high hardness materials is 18 times more bend resistant than the SD standard, impact resistant for drops up to 16', and the highest dustproof and waterproof level (IP68). Fragile Parts Designed Out By designing out the weak parts of conventional SD cards - the ribs and write-protect switch -reliability is vastly improved. This reduces risk of difficulty in recording data if broken. Superior Water and Dustproofing The fully-sealed one-piece molding meets the highest specifications for both waterproofing and dustproofing. With an IP68 rating, the SF-G series TOUGH specification cards can withstand fine dust, mud, grime and immersion in 16' of water for up to 72 hours. Ultra-Fast Write Speeds Take burst-shooting and high-resolution video recording to the next level with ultra-fast write speeds up to 299 MB/s, which is fast enough for even the highest performance camera with a UHS-II interface. V90 for Capturing High-Resolution Video Support for the latest V90 video speed class makes this card perfect for high-resolution video recording.
