Phison is 8k Video Ready with its new SD 5.0 compliant Video Speed Class SD/microSD Solutions

Septembre 2nd, 2016

As a world leading NAND flash solution provider, Phison has always been working on expanding the compatibility of its memory cards --- and Phison now announces that its memory cards are now ready to support SD 5.0 compliant Video Speed Class.

Product support list of Phison solutions:

SD 5.0, more commonly referred to as VIDEO SPEED CLASS (VSC), is the fastest high-quality video speed class up to date. VSC was introduced by the SDA to support 8K AND MULTI-FILE VIDEO RECORDING at the Camera and Photo Imaging Show of 2016.

SD Speed Rating & VSC

The SDA has determined three rating standards — normal Speed Class marked with Class 2, 4, 6 and 10 (DS, HS mode), UHS Speed Classes marked with U1 and U3 (UHS mode), and Video Speed Class marked with V6, V10, V30, V60, V90 (HS, UHS mode). VSC enables conventional Speed Class and UHS Speed Class and is designed to optimize modern NAND memory technology for high resolution & high quality video recording.

SDA produced shortclip of VSC and corresponding video format applications :


What makes VSC a must?
SD 5.0 Video Speed Class was introduced to:

  • Provide faster recording for video technology of the future
    • Enable the future use of NAND technology in SD memory cards
    • Support new standard protocol for hosts/applications to efficiently write to SD memory cards.

In order to take advantage of this new standard, users simply need to use SD5.0 compliant memory cards with the recommended applications and they can experience the smoothest file recording and playback possible.

The developers refined the SD 5.0 specification to ensure that the cards were backwards compatible with previous speed class definitions. This feature allows users to use the memory card with any type and grade of video recording applications out in the market, drastically reducing any hassle and confusion.

Phison’s controllers PS8036, PS8036, PS8039, and P8210 for SD/microSD solutions will be fully compliant with SD 5.0 VSC by the end of 2016.
