Yes, you read it right! 128TB SD memory card will be the reality in near future and the technology behind this high storage faster data transfer rate SD memory card is known as “SD Express”. The technology will not only empower the high data storage memory card but also helps faster data transfer. This will empower various technologies like AR, VR, 360 Degree photography and videography etc.
During Mobile World Congress Shanghai, today on 26th June 2018, The SD Association a group of over 900 companies announced SD express technology which is the best combination of PCI Express® and NVMe™ interfaces. If you are not aware, the PCIe interface can deliver upto 985 MB per second maximum data transfer rate and the NVMe upper layer protocol can enables best memory advance mechanism. Here they announced the maximum SD memory card storage capacity will be grows from 2TB with SDXC to 128TB with this new technology of SD ultra capacity (SDUC) card. This new innovation will also enable backward compatibility and is a part of new SD 7.0 specifications.
Here is the official video from SD Association explaining SD express technology
Brief about SD Express Technology:
