Breaking the speed limit: Sony introduces fastest-ever Memory Stick PRO-HG Duo™HX

17 May 2011

Class-leading card offers up to 50 MB/sec speeds for high-speed burst shooting and Full HD video

Memory Stick PRO-HG Duo™HX

· Memory Stick PRO-HG Duo™ HX with up to 50MB/sec transfer rates

· New HX Engine technology for fast, reliable data transfers

· Faster than UHS-I SD cards used with devices by Sony

· Available in 8/16/32GB capacities

· Ideal for high-speed burst shooting with DSLR, Full HD movies and 3D imaging

· High reliability with 10 year warranty

· Includes free File Rescue and x-Pict Story™ software

· Same price as previous Memory Stick PRO-HG Duo™ HX models

Now photographers can fully exploit the high-speed, high-resolution shooting potential of the latest digital cameras and camcorders from Sony.

The range-topping Memory Stick PRO-HG Duo™ HX now boasts blazing data transfer speeds of up to 50MB/sec1. 1.6x faster than previous Memory Stick PRO-HG Duo™ HX cards – and available at the same price – it’s quicker than today’s fastest commercially available UHS-I SD cards when used with devices by Sony.

This phenomenal performance makes new Memory Stick PRO-HG Duo™ HX an ideal shooting, storage and data transfer solution for demanding digital imaging users.

Available in capacities from 8GB to 32GB, the fastest-ever Memory Stick is optimised for sustained burst shooting with today’s high-resolution DSLR, SLT and interchangeable lens cameras.

Teamed with the NEX-5 ultra-compact camera by Sony, the card can capture 190 JPEG images in one minute in high-speed burst shooting mode. That’s well over double the rate of 80 images/minute using a standard Class 4 SD card. The high performance of Memory Stick PRO-HG Duo™ HX also makes it ideal for recording Full HD and 3D movies with the latest Handycam® camcorders. For more information please see the HX Memory card file which is attached to this release.

Memory Stick PRO-HG Duo™ HX makes post-shooting file transfers and back-ups faster, too. Copying a 32GB AVCHD movie file to your PC2 takes just 11 minutes. That’s more than twice as quick as transfers using today’s fastest SDHC cards.

These significant improvements are made possible by new HX Engine that’s been specially developed by Sony. This intelligent flash memory controller enhances data transfer efficiency and error handling for quicker, more stable read/write performance with large files.

For maximum peace of mind, the card’s high reliability is backed by a 10-year warranty by Sony.

Available from for registered Memory Stick PRO-HG Duo™ HX owners, File Rescue recovers accidentally damaged or deleted files. With a 90% successful recovery rate3, it’s an essential utility to help restore precious data including JPEG photos, MPEG or AVCHD video and MP3 music files4.

Also available as a free download to registered owners, x-Pict Story™ software helps anyone create memorable photo slideshows. This friendly package combines your favourite photos and music with beautiful visual effects to create professional-looking presentations. Integration with Picture Motion Browser software makes it quick and easy to upload slideshows to sharing sites like YouTube™.

The new 50 MB/sec Memory Stick PRO-HG Duo™ HX by Sony is available from May 2011. Prices for all capacities (8/16/32GB) are unchanged compared with previous Memory Stick PRO-HG Duo™ HX models.
