The SD Association announced its SD 8.0 specification. The standardization organization behind the SD memory cards describes that they use the PCIe interface and the NVMe protocol, which this time all... SD Express memory cards can reach max of 3938 MB/s in latest specification
Yeah, that's NVMe SSD in SD package. But NVMes are huge compared to SDs and by reason - parallelism increases performance. In SD everything is in one package, controller, FLASH and probably on RAM.
Eh, M.2 SSDs aren't huge in comparison. The huge difference is in the interface. An SD card has a very limited amount of pins to use for data transfer (like four, I think), compared to the M.2 socket, which has multiple times of that.
maybe phones and tiny stuff switch to this as main memory instead of soldered-on chips? microsoft already did it with the tiniest m.2 2230 cards on their surface pro/laptop products, I've had more than one phone fail because of the internal flash memory dying
