In July 2013, SanDisk introduced SanDisk Extreme SD cards with performance speed of up to 80 MB/s read. At launch, these cards were labeled/branded as SanDisk Extreme. As of January 17, 2014, these products have been rebranded as SanDisk Extreme PLUS, but the card performance remains the same.
During the transition, there may be some products that perform at up to 80 MB/s read with the SanDisk Extreme packaging and card label that are available for purchase. These are the same products as the SanDisk Extreme PLUS products and provide the read speed performance of up to 80 MB/s, as stated on the packaging. The color of the label has also transitioned from red/black (Extreme) to gold (Extreme PLUS).
