By PR admin | Published: June 27, 2018

The SD Association announced a new memory card standard called SD Express with memory card capacity up to 128TB and 985 MB/s maximum data transfer rate:

  • SD Express: Incorporates the PCIe® and NVMeTM interfaces, known worldwide for its high bandwidth and low latency storage, into SD memory cards alongside legacy SD interfaces
  • SD Ultra Capacity (SDUC): Extends the potential maximum SD memory card capacity from 2TB to up to 128TB

"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 the popular SD memory card. In addition, the maximum storage capacity in SD memory cards grows from 2TB with SDXC to 128 TB with the new SD Ultra Capacity (SDUC) card. These innovations maintain the SDA’s commitment to backward compatibility and are part of the new SD 7.0 specification."
