Version 7.0 of the SD standard finally raises the storage limit to above 2 TB, which was being rapidly approached by both full size SD cards (1 TB) and microSD cards (512 GB). It also adds an SD Express mode, which can raise speeds up to 985 MB/s, from a previous limit of 624 MB/s:
Soon you will be able to purchase new SD cards with the SD Version 7.0 specification. The new specification supports up to 985MB/s of throughput, which comes courtesy of PCIe and NVMe interfaces, and up to 128TB of capacity. That's quite the jump over the current 2TB limit.
985MB/s of throughput for a simple SD card may seem ludicrous, but higher-resolution video, VR, automotive use-cases, and IoT applications are steadily encroaching upon the performance limits of today's products.
[...] The specification has reserved space for new pins for future use, so it also provides room for forward progress (PDF). The specification also accommodates up to 1.8W of power consumption, which will help boost performance. The NVMe 1.3 protocol also brings several new features to SD cards, like Host Memory Buffer (HMB), which sets aside a small portion of system memory to boost performance, and Multi-Queue support, which improves performance during simultaneous file transfers.

In this day and age, you should be thankful the new standard doesn't include a mandatorily inbuilt wifi transmitter to automatically upload the contents of your SD card to the secret police of the nearest nation-state (as well as google and facebook of course), as well as overlaying your pictures with Some Important Messages From Our Sponsors.
