Sony offers faster Memory Stick PRO-HG Duo HX cards

Sony Memory Stick-Pro HG Duo HX cardSony has created Memory Stick-Pro HG Duo HX cards with read speeds increased to up to 30MB/s, from 20MB/s. The write speed remains at a minimum of 15MB/s (on HG-compatible devices), as per the previous generation cards. The faster read rates will speed up processes such as the transfer of large images or playback of HD video. The latest cards are available in 8GB, 16GB and 32GB capacities.

Press Release:

Memory Stick PRO-HG Duo™ HX from Sony gets even faster

    • The fastest data transfer speed available from a Memory Stick™ or SD product: 30MB/second
    • Shorter time to transfer HD video and photos to your PC
    • Reliable and affordable
    • 8GB, 16GB and 32GB models available
May 12 2010: HD videos and high resolution still images can be transferred significantly faster to your PC with the latest Memory Stick™ HX technology that increases the speed of transferring data by 50% compared to existing products - from 20MB/s to 30MB/s.

For anyone routinely dealing with large files this soon adds up to a major improvement in convenience as it reduces the wait for copying, backing up or getting ready to view or edit your work.

HD video transferred to your PC – fast!
Handycam® users who wish to edit HD video on a PC, such as a VAIO™, will readily appreciate the speed advantage of the new HX technology. A 30GB Full HD video file can transfer onto a PC in just 17 minutes. This is in the order of fourtimes faster than a Memory Stick PRO Duo Mark2™ card and significantly faster than SD/SDHC cards.

You don’t have to be a Handycam® owner to benefit either. It could just as easily be HD video taken with a Cyber-shot™ or huge volumes of high resolution still images captured with the burst shooting mode on a Sony Aplha DSLR. The wait still goes away.

Benefit of burst shooting with a DSLR
Thank to its high performance, Memory Stick PRO-HG Duo™ can cope with the advanced continuous shooting mode with Alpha DSLR from Sony witout missing any key shots. Other cards cannot keep up with the camera and the shooting speed slows down while burst shooting. HX is the ideal choice for burst shooting.

Like all Sony Memory Cards, the new Memory Stick PRO-HG Duo™ HX range offers more than the obvious benefits of quality and reliability. Customers are entitled to a free download of two essential applications: File Rescue and x-Pict Story™ for memory card. File Rescue gives you peace of mind, and x-Pict Story™ is a fun, creative tool for making and sharing slideshows of your favorite pictures.

Memory Card File Rescue
Sometimes things go wrong and photos, music or video clips get lost. File Rescue is a powerful tool for recovering lost data that is simple enough for anyone to use. Available as a free download to Memory Card customers, File Rescue scans the card and restores* lost files with an impressive 90% success rate.

x-Pict Story™ for memory card
Great photos deserve to be seen and shared. x-Pict Story™ gives you the means to create striking, original slide shows, complete with your choice of music. The three-step process is very easy, and an upload option* makes it simple to use video sharing sites like YouTube.

There are different speeds of SD card available. The official unit of measurement is the Speed Class Rating; an older unit of measurement is the × rating.

Speed Class Rating

The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. It is equal to 8 Mbit/s, and it measures the minimum write speeds based on "the best fragmented state where no memory unit is occupied

The following are the ratings of some currently available cards:

  • Class 2: 16 Mbit/s (2 MB/s)
  • Class 4: 32 Mbit/s (4 MB/s)
  • Class 6: 48 Mbit/s (6 MB/s)
  • Class 10: 80 Mbit/s (10 MB/s)
Even though the class ratings are defined by a governing body, like × speed ratings, class speed ratings are quoted by the manufacturers but unverified by any independent evaluation process.

Important differences between the Speed Class and the traditional CD-ROM drive speed measurement ("×" speed ratings) are:

  • 1. the ability of the host device to query the SD card for the speed class and determine the best location to store data that meets the performance required
  • 2. class speed defines the minimum transfer speed.
  • Since the class rating is readable by devices, they can issue a warning to the user if the inserted card's reported rating falls below the application's minimum requirement.
On 21 May 2009, Panasonic announced new class 10 SDHC cards, claiming that this new class is "part of SD Card Specification Ver.3.0". Toshiba also announced cards based on the new 3.0 spec As of December 2009, the SD Association's Web site does not include information on this new class or new specification.

× rating

The × rating is a unit of measurement equal to 1.2 Mbit/s. It is derived from the standard CD-ROM drive speed of 1.2 Mbit/s. Basic cards transfer data up to six times (6×) the data rate of the standard CD-ROM speed (7.2 Mbit/s vs 1.2 Mbit/s). The 2.0 specification defines speeds up to 200×, but unlike the class rating system, does not mandate that x-ratings measure the card's sustained write-speed. For most cards, the maximum read speed is typical faster than its maximum write speed, leading some manufacturers to use read-speed as the ×-rating measurement. Other vendors, such as (Kingston, use write-speed.[ This table lists common ratings and minimum transfer rates.
