MWC Shanghai 2022: Faster, High-Capacity SD Cards Coming in 2022 With SD Express Standard
At the ongoing MWC Shanghai 2018, the SD Association has announced the new SD Express standard that is expected to not only increment the storage chapters of SD cards, but too make them significantly faster than the current models past calculation PCI Limited and NVMe interfaces to the legacy SD interface.
Also improved performance, ane of the other big advantages is that SD Express retains backward compatibility with current and legacy devices, and are part of the new SD 7.0 specification.
According to the official press release, the new technology volition allow the maximum storage capacity in SD memory cards to from 2TB with SDXC to a whopping 128 TB with the new SD Ultra Capacity (SDUC) card. Speeds volition meet a meaning bump likewise, with the PCIe interface delivering a 985 Megabytes per second (MB/s) maximum data transfer rate.
As we saw in the proof-of-concept demo at the event, a SanDisk-manufactured SDUC bill of fare seems to take hit 898Mb/s read speeds and 580Mb/south write speeds in CrystalDiskMark.
"With SD Limited nosotros're offering an entirely new level of memory carte with faster protocols turning cards into a removable SSD", said Hiroyuki Sakamoto, SDA president. "SD 7.0 delivers revolutionary innovations to anticipate the needs of forthcoming devices and content rich and speed hungry applications".
SD Express uses PCIe 3.0 and NVMe v1.3 protocols divers by PCI-SIG and NVM Express, respectively, on the second row of pins used by UHS-II cards today. These cards also bring new options to system developers offered past PCIe and NVMe capabilities, such as Double-decker Mastering, Multi Queue (without locking mechanism) and Host Memory Buffer, according to the release.
In case you are interested in all the technical details, yous tin can always take a wait at the white paper released by the SDA. Called 'SD Express Cards with PCIe and NVMe Interfaces', it provides more details on the new capabilities and features establish in the SD 7.0 specification. Yous can also check out the SD Association website for more than details on the new format.
