Lexar&39's new Professional 133x SDXC memory card.

If Lexar's recently reviewed 128GB Echo MX thumbdrive makes you wonder when you'll have something like the same capacity for your camera, the answer is here.

Lexar announced today that it is now shipping the first 128GB Professional Secure Digital Extended Capacity (SDXC) memory card.

First announced at CES 2011, the new SDXC memory card comes in two capacities, 128GB and 64GB, and offers speeds of up to 133x (about 20MBps). This means the new card enables you to take multiple hi-def photos continuously or record extended-length 1080p HD videos without having to stop and swap the memory card.

The Lexar Professional 133x SDXC memory card includes the latest version of the company's Image Rescue software, which helps recover lost or deleted photo and video files.

Lexar claims that the card has been tested to ensure performance, reliability, and compatibility with more than 800 existing digital devices. It also works with any SDXC-enabled devices such as card readers.

The Lexar Professional SDXC card comes with a limited lifetime warranty. The card is available now and costs $200 for the 64GB version and $330 for the 128GB version.
