Sony Cranks Memory Stick To 32GB, Won't Concede To SD/CF
That said, Sony's still a believe in the MSPro and MSPro Duo formats, as it has today introduced a new pair of flash cards for those who think 16GB cards are simply for suckers. The two cards offer the most capacity of any Sony-made flash card (32GB), as the 32GB PRO-HG Duo HX and 32GB PRO Duo models provide ample storage for those with devices that will support 'em.
The 32GB PRO-HG Duo HX card is designed to deliver optimal read and write speeds for cameras and camcorders shooting large/high-resolution clips. If you do lots of RAW shooting or 1080p capturing, this card is for you. The HX series offers a 20 MB/s read speed and 15 MB/s write speed, which is approximately three times faster than Sony’s PRO Duo media card. Considering that even Sony realizes how un-friendly this format is, the company even throws in a USB adapter so you can actually get content from your device to your machine. Thanks, Sony.

The new 32GB PRO-HG Duo HX Memory Stick and 32GB PRO Duo Memory Stick will be available at the end of September for around $249 and $199, respectively.
