SDA ANNOUNCES NEW SD EXPRESS/UHS-II VERIFICATION PROGRAM (SVP)
Program verifies conformance and performance of products
SAN RAMON, CALIF— Sept. 15, 2021 — SD Association (SDA) developed the SD
Express/UHS-II Verification Program (SVP) to verify the electronic interfaces ofmembers’ UHS-II and SD Express card/host/ancillary products. Products passing SVP
may be listed on the SDA website as a Verified Product. SVP provides both consumers
and businesses higher confidence that products passing SVP meet the interface
standards, ensuring compatibility.
SVP tests products for compliance against the SDA’s Physical Test Guideline. Productseligible for SVP include card/host/ancillary products using SD Express, with PCIExpress® (PCIe®) interface or SD UHS-II interface. The SDA selected Granite RiverLabs (GRL) as the first test provider with labs located in Japan, Taiwan and US. SVP isa voluntary program available exclusively to SDA members. Members may choose tohave products passing SVP tests listed on the SDA website
PCIe and UHS-II interfaces are both high differential interfaces and meeting theirspecifications demanding requirements is extremely important to assure proper
operation and interoperability. The SVP serves the market by assuring betterinteroperability and by publishing a list of SVP Verified Products. This list allows
members to promote their products and allows both consumers and OEMs to havemore confidence by selecting products on the list.
“SD Express delivers the fastest bus performance for a growing number of devices andUHS-II provides the industry with another solid choice for moving speed sensitive data
quickly,” said Hiroyuki Sakamoto, SDA president. “SVP increases confidence among
consumers and businesses that products using SD Express or UHS-II will meetinterface standards and deliver the performance defined by our industry leadingspecifications.”
For a limited time, the SDA is subsidizing SVP costs and is providing its members withadditional discount options via a Test Shuttle volume discount program. Test Shuttle
leverages multiple members submitting products of the same type for bulk testing.

SVP can join the SDA by visiting: https://www.sdcard.org/join/.
SD ExpressSD Express offers the fastest transfer speeds for both SD and microSD memory cardsby integrating the popular PCIe® architecture. SD Express memory cards using the SD
8.0 specification leveraging the PCIe 4.0 specification deliver a maximum of nearly 4gigabytes per second (GB/s) data transfer rate. microSD Express memory cards using
the SD 7.1 specification deliver a 985 megabytes per second (MB/s) maximum data- more -transfer rate. These speeds are delivered using a second and third row of pins. Bothform factors use the NVMe Express™ (NVMe™) upper layer protocol enablingadvanced memory access mechanism and maintain backward compatibility. SDExpress will be available in SDHC, SDXC, SDUC, microSDHC, microSDXC andmicroSDUC capacities.
UHS-II Bus Interface
The UHS-II high-speed interface delivers up to 312MB/s using a second row of pins.
This bus transfer speed option is available in SDHC, SDXC and SDUC capacities, aswell as microSDHC, microSDXC and microSDUC. UHS-II is found in the SD 4.0
specification.
SD Association
The SD Association is a global ecosystem of nearly 800 technology companies charged
with setting interoperable SD standards. The Association encourages the developmentof consumer electronic, wireless communication, digital imaging and networking
products that utilize market-leading SD technology. The SD standard is the number one
choice for consumers and has earned more than 80 percent of the memory card market
with its reliable interoperability and its easy-to-use format. Today, smart phones, tablets,drones, IoT devices, HDTVs, audio players, automotive systems, computers, digitalcameras and digital video cameras feature SD interoperability. For more information
