SD Association has made an announcement the SD Express standard at an ongoing event called MWC Shanghai 2018. The SD Express standard will crucially increase the storage capacity of SD cards. It is also expected to make SD cards way faster than current cards. NVMe interfaces and PCI Express will be added to the tradition SD interface.
SD Association to Introduce Faster, High-Capacity SD Cards in 2019
There are many other advantages of this update is that SD Express hold on to backward compatibility with legacy and current devices. It is also a part of the specifications of new SD 7.0.
As per the official press release by the company, this new update in the technology will increase the storage capacity of SD cards to a maximum extent of somewhere between 2TB with SDXC to 128TB with the SD Ultra Capacity card.
The new technology will also be increased to a new level. PCIe interface will be able to deliver a 985 Megabytes per second that is the maximum data transfer rate so far.
According to Hiroyuki Sakamoto, SDA President, “With SD Express we’re offering an entirely new level of the memory card with faster protocols turning cards into a removable SSD.” He further added that “SD 7.0 delivers revolutionary innovations to anticipate the needs of forthcoming devices and content rich and speed hungry applications”.
The company makes good use of PCIe 3.0 and NVMe v1.3 protocols that are set by NVM Express and PCI-SIG, on the 2nd-row of pins that UHS-II cards use today.
According to the release, these cards will offer new options like Bus Mastering, Host Memory Buffer, and Multi-Queue to the system developers.
More details are provided in the white paper by SDA which is called as ‘SD Express Cards with PCIe and NVMe interfaces’.
