SanDisk has introduced the fastest card in its Memory Stick product family: the SanDisk Extreme III Memory Stick PRO-HG Duo.

The new card has read and write speeds of 30Mbps and is available in 4GB and 8GB capacities.

It is claimed to be ideal for professional photographers and advanced amateurs who use Sony digital SLR cameras, as the two companies developed the cards together.

"The SanDisk Extreme III Memory Stick PRO-HG Duo continues our tradition of delivering best-in-class performance in the SanDisk Extreme product line", said Susan Park, director of consumer product marketing for SanDisk’s performance cards.

"Our customers know SanDisk Extreme cards not only deliver cutting-edge read and write speeds, but are designed for durability – even under harsh conditions."

SanDisk Extreme III cards are capable of functioning in temperatures from -13 to 185 degrees Fahrenheit or -25 to 85 degrees Celsius, and carry a lifetime warranty.

The cards also come with RescuePRO software for recovering deleted images.

They will be available worldwide in June.
