Now that 4K video is becoming more and more normal we need SD cards that can keep up. The current high speed cards can keep up pretty well with 4K, but those 4K files are huge and can take a while to transfer to your PC for editing. The all new Sony SF-G series can read up to 300MB/s and write up to 299MB/s. This means a 10Gb file can transfer in mere seconds! These cards are apparently also great for photographers since they nearly eliminate buffer clearing times. These cards are expected to launch in the Spring in 32GB, 64B and 128GB capacities.
