Kingmax has just unveiled their latest SDXC memory card, which is waterproof and dustproof. So you will be good to go in the rain or in a dusty cave somewhere. This SDXC card comes in a 64GB capacity and baosts a Class 10 rating, built-in ECC (Error Correction Code) and it also has an exFAT file structure.
As far as performance, the card will deliver read and write speeds of up to 65MB/s and 40MB/s, respectively. Sounds great, but right now we have no info on pricing and a release date yet. Hopefully we will know soon.
