Sony’s Pro-HG Duo HX Memory Stick line-up has been available since the last quarter of 2008 in 4GB, 8GB and 16GB capacities.

This time, they’re introducing a 32GB variant which allows you to achieve read speeds of 20MB/s and write speeds of 15MB/s using the USB adapter. It can also store up to 225 minutes of full HD (1920 x 1080) resolution videos.

Nothing in the press release pertained to release date or pricing. All versions include a USB adapter for easy-plugging into computers.

Is this Sony’s fastest? Probably. Fastest in the flash memory realm? That’s still ruled by SD cards. One of which is the Sandisk Extreme SDHC Class 10.

• Highest available capacity – 32GB comes to Memory Stick HX family
• Super-fast 20MB/second data transfer significantly shortens the wait
• Perfect for High Definition camcorders – or anyone handling large volumes of images
