Just as we start to accept UHS-II into our lives, and before UHS-III is even a real thing, a new standard hits the streets. That’s right, folks, SD Express has now been announced, offering data transfer speeds of up to 985MB/sec. It also bumps up the maximum capacity from SDCX’s 2TB to the new SDUC’s 128TB.
SD Express uses PCIe and NVMe interfaces to deliver these faster transfer speeds. To read about how the SD Association talks about SD Express, it’s almost like they want or expect people to start using these as portable SSD replacements for general use.
