The SD Association announced today SD Express which adds the popular PCI Express and NVMe interfaces to the legacy SD interface. 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 2 TB 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.

So now you can have more than 100 TB of data corrupted by a counterfeit Chinese SD card. Sweet!

Only if price is your only measure of a bargain. Buy cheap, buy twice.

But what is the fastest a card write/reader can do.? Take my Canon t2i, for instance, it bottles out at about 20MBs/Sec. And yes I know many new cameras will be much faster. But just think if a laptop could read/write at that speed would be like a second or third disk for editing.
