Sony announced the new Memory Stick PRO-HG Duo HX aimed at HD cameras.
The new Sony Memory Stick PRO-HG Duo HX comes with a choice of 4GB and 8GB capacity and a read speed of 20MB/second and 15MB/second write.

When used with the supplied USB adaptor for maximum speed, the PRO-HG Duo HX can shorten data transfer time by one-third compared to a Memory Stick PRO Duo (Mark 2).

Sony also offers a free, downloadable Memory Stick Data Rescue Service which can quickly recover deleted photographs and files.
The Memory Stick PRO-HG Duo HX uses an 8-bit parallel interface to achieve this level of performance.
Sony also offers a 10 year warranty on these new sticks.
The new Sony Memory Stick PRO-HG Duo HX will be available from Oct. 2008.
