Phison Awarded SD Association’s SVP Verification


For SD Express storage solution

Phison Electronics Corp. announced that its SD Express storage solution is the first product to pass the SD Association’s SD Express/UHS-II Verification Program (SVP).

This verification indicates that these products meet interface standards, providing confidence to both consumers and businesses that it will operate and perform properly.

According to the SD Association,PCIe and UHS-II are both high differential interfaces and meeting their specs demanding requirements is extremely important to assure proper operation and interoperability.

The Association officially launched the SVP program at the end of 2021, becoming the notary unit that leads the compatibility verification between the host system and the SD memory card manufacturer to positively assist in the development of the product ecosystem. As a supplier of SD card controllers and solutions, Phison has pledged to support the SD Association’s SVP program and to work with its global brand customers in launching the latest SD Express storage solutions that meet the SVP verification requirements.

As image quality of video continues to improve, user requirements for removable storage devices are increasing not only in capacity but also in transmission speeds required of the interfaces. The speed of SD cards indicated by the SD Logo are generally affirmed with the guarantee of the “minimum writing speed,” largely because the general host system does not have high requirements for the read speed of removable storage devices. It only needs to roughly pre-read and confirm the correctness of the photo or video file data with more sophisticated edits or modifications moved to the PC for execution.

However, with high-speed mobile storage requirements, it is likely that system compatibility issues derived from high-speed transmission will lead to poor user experience, such as SD card speed slowing down, or card recognition failure. Verification of Phison’s SD Express solutions ensures that compatibility issues between system integrators and SD memory card designers are reduced, while also promoting the popularization of the latest SD card specs.

Phison is a member of the SD Association’s board of directors and has long assisted the SD Association in promoting the latest SD specs and technologies worldwide,” said K.S. Pua, CEO. “The SD Association chose to launch the SVP certification program as the trend of high-speed mobile storage devices has taken off. We are pleased to have successfully attained the SVP certification within two months of our submission and becoming the first supplier to provide SD Express storage products to market with this certification.

SVP tests products for compliance vs. the SDA’s Physical Test Guideline. Products eligible for SVP include card/host/ancillary products using SD Express, with PCIe interface or SD UHS-II interface. SVP is a voluntary program available exclusively to SDA members.
