For every step of the workflow - from capture and transfer to archive - Western Digital is committed to advancing technology to help professionals and creators get work done faster and more efficiently, ultimately saving time and money, so they can focus on their creativity.

SD Association (SDA) today announced the latest evolution of SD Express memory cards doubling microSD Express memory card speed up to 2 GB/s, plus four new SD Express Speed Classes to ensure guaranteed minimum sequential performance levels in the new SD 9.1 specification including support of Multi-stream access and related Power and Thermal Management assuring the guaranteed performance. SD 9.1 helps consumers identify the right card for their device while giving manufacturers new tools to assure minimum level of performance of SD Express memory cards and have means to guide consumers what type of cards will assure specific application operations.

The latest generation of microSD Express uses the PCIe interface delivering a 1,969 megabytes per second (MB/s), nearly 2 gigabytes per second (GB/s) speeds by using the PCIe Gen 4 x1 lane as defined in the latest update to the microSD Addendum version 8 specification. microSD Express was introduced with 985 MB/s speed maximum data transfer rate and the NVMe upper layer protocol in the SD 7.1 specification. The increase in speed gives product designers more storage options and SSD level performance for a variety of size constrained devices requiring easily repairable or upgradeable storage.

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."

The SD Association announced today microSD Express, offering the popular PCI Express and NVMe interfaces alongside the legacy microSD interface for backwards compatibility. Like SD Express, microSD Express uses the PCIe interface delivering a 985 megabytes per second (MB/s) maximum data transfer rate and the NVMe upper layer protocol enables advanced memory access mechanism, enabling a new world of opportunities for mobile devices.

microSD Express cards defined in the SD 7.1 specification will be offered in a variety of capacities such as microSDHC Express, microSDXC Express and microSDUC Express. "microSD Express gives the mobile industry a compelling new choice to equip mobile devices with removable SSDs," said Hiroyuki Sakamoto, SDA president. "SD 7.1 prepares consumers and mobile device manufacturers to meet ever increasing storage demands for years to come."
