SD Express Delivers New Gigabyte Speeds for SD Memory Cards
19.5.2020 15:00:00 EEST | Business Wire | Press release
The SD Association announced today the SD 8.0 Specification for SD Express memory cards receives even faster transfer speeds by using the popular PCI Express® (PCIe®) 4.0 specification delivering a maximum of nearly 4 gigabytes per second (GB/s) data transfer rate. These full sized cards continue to use the NVMe Express™ (NVMe™) upper layer protocol enabling advanced memory access mechanism. As always SD Express memory cards using SD 8.0 specification maintain backward compatibility.

“SD Express’ use of even faster PCIe and NVMe architectures to deliver faster transfer speeds creates more opportunities for devices to use SD memory cards,” said Mats Larsson, Senior Market Analyst at Futuresource. “This combination of trusted and well-known technologies makes it easier for future product designs to leverage the benefits of removable storage in new ways.”
SD Express gigabyte speeds bring new storage opportunities for devices with demanding performance levels, across a variety of industries. The cards can move large amounts of data generated by data-intense wireless or wired communication, super-slow motion video, RAW continuous burst mode and 8K video capture and playback, 360 degree cameras/videos, speed hungry applications running on cards and mobile computing devices, ever evolving gaming systems, multi-channel IoT devices and automotive to name a few. SD Express will be offered on SDHC, SDXC and SDUC memory cards.
“By dramatically increasing the speeds for SD Express we’re giving device manufacturers and system developers more storage choices,” said Hiroyuki Sakamoto, SDA president. “SD 8.0 may open even more opportunities for extra high performance solutions using removable memory cards.”
“PCI-SIG® is pleased to see that SDA is continuing to adopt even faster PCIe technology configurations using PCIe 4.0 interface and dual lanes for one of the top leading removable memory cards – SD,” said Al Yanes, PCI-SIG president and chairman. “PCIe specification conformance tests are available today by major test vendors, offering a significant advantage for any new PCIe technology adopter.”
“NVMe is the industry-recognized performance SSD interface from the client to the datacenter, shipping in millions of units,” said Amber Huffman, NVM Express™ Inc. president. “Consumers will benefit by SD Association continuing the adoption of the NVMe base specification for their latest SD Express cards.”
SD Express uses the well-known PCIe 4.0 specification and the latest NVMe specification (up to version 1.4) defined by PCI-SIG and NVM Express, respectively. SD 8.0 specification provides two transfer speed options for SD Express memory cards. The two transfer speeds are accomplished by supporting either PCIe 3.0 x2 or PCIe 4.0 x1 architectures with up to ~2GB/s and with PCIe 4.0 x2 technology with up to 4GB/s. SD Express cards offering PCIe 4.0 x1 architecture use the same form factor as defined for SD 7.0 specification cards with a second row of pins to deliver transfer speeds up to 2 GB/s. SD Express cards supporting dual PCIe lanes (PCIe 3.0 x2 or PCIe 4.0 x2 technologies) have three rows of pins.
The SDA makes adoption of SD Express easy allowing companies to use existing test equipment and saving in product development costs. The SD 8.0 specification continues giving system developers access to PCIe and NVMe technologies, such as Bus Mastering, Multi Queue (without locking mechanism) and Host Memory Buffer.
Two revised white papers, “SD Express Cards with PCIe and NVMe Interfaces,” and “SD Express and microSD Express Memory Cards: The Best Choice for Your Future Product Designs” provide an in-depth look at the opportunities created by SD Express. More information is available on our website.

New MetLife Study Reveals a 72% “Confidence Gap” in Ability to Recover from Life's Setbacks24.6.2026 16:25:00 EEST | Press release
A new multinational study from MetLife reveals a striking “confidence gap”: while most adults describe themselves as resilient, their confidence drops by 72% when faced with real-life setbacks. The Confident Pathways Report, conducted across the United States, United Kingdom, Japan, and Mexico, was designed to better understand how confidence is built and sustained throughout life. The findings underscore the role of opportunity, preparedness, and support in building confidence - factors that help people navigate uncertainty, recover from setbacks and pursue their goals. At a time when soccer is bringing people and communities together around the world, the findings also highlight how early childhood experiences such as sports, education, and mentorship can help foster resilience and gain confidence from a young age. Key findings across the four countries surveyed include: Confidence drops by 72% when adults consider their ability to recover from setbacks. Respondents were far more lik
StatLab Launches CytoPath Disc, Advancing Standardized Cell Block Preparation Worldwide24.6.2026 16:08:00 EEST | Press release
StatLab Medical Products, a leading global developer and manufacturer of pathology supplies and equipment, today announced the global launch of the CytoPath Disc, an innovative cell block preparation technology designed to standardize and simplify cell block preparation. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260624368623/en/ Developed as an alternative to traditional cell block methods, which convert concentrated cells suspended in fluid into a paraffin-embedded format for slide-based evaluation, the patent‑pending CytoPath Disc offers a more streamlined and efficient approach.
