SD cards hop on the PCIe 4.0 bus to hit 4GB/s with version 8.0 of storage spec
The SD Association, which oversees the design of SD cards, has emitted version 8.0 of its specification that promises to accelerate the mini-memory storage standard to a tick under 4GB/s. As outlined in a whitepaper [PDF] this month, the new spec will let existing SD Express and microSD Express cards employ PCIe 4.0 and NVMe …

Re: So not full speed on any Intel platform then
I'm wondering about power as well - while the standard may support 4GB/s there is also a lower 3GB/s option versus SDXC maxing out at 1GB/s which is much higher than you would typically see on an SDXC card reader.
The interface appears to be rated at 1.8W vs current cards that are under 100 mW.

Presumably
These speeds and capacities are the capability of the interface, not the actual flash storage on the card. How far behind the curve is the existing tech, even if this interface is used?
At the moment a 1TB Sandisk SD card with a 170 Mb/s interface is more than £460. Scaling linearly for storage alone (I know it's a bad example) your 128TB card is going to cost nearly £60,000. But if this ever does become affordable then paying for Cloud storage becomes a bit pointless, you could be feasibly be running a 0.5PB portable NAS server from your phone over 7G.
