According to a press release, Delkin Black SD cards are built using a proprietary injection molding process that differs from the traditional surface mounted components and welded case design that most cards utilize. This process uses an innovative material to give the cards advantages that are far superior in terms of reliability and ruggedness when compared to traditional memory cards. In addition to being significantly stronger and far less breakable than standard SD cards in bend/pressure tests, Delkin Black cards are dust, water, and shock-proof, and have an extended temperature range that allows the card to perform flawlessly in environments ranging from -40C to 85C.
Delkin’s Marketing Director, Anna Lopez, explains: “From the Arctic to the Sahara, and even through your washing machine, the unique design enables Delkin Black cards to perform through hazardous environments and remain totally usable without experiencing any data loss.”
Delkin Black cards are available in capacities of 32GB, 64GB and 128GB, and individually serialized. Read and write speeds are proven at 99MB/s and 80MB/s respectively, and the cards are rated for UHS-I Speed Class 3, meaning they are guaranteed to perform at a minimum sequential write speed of 30MB/s – a rating that is required for many 4K applications.
