Two companies have announced 1 terabyte microSDXC cards at Mobile World Congress 2019:
Micron's fingernail-sized card uses 96-layer 3D NAND configured as QLC (4bits/cell) storage and delivers up to 100MB/s read and 95MB/s write burst performance helped by a dynamically sized SLC cache.
WD's SanDisk's UHS-I microSDXC, meanwhile, boasts "up to" speeds of 160MB/s reads and 90MB/s writes.
[...] Random IO is up to 4,000 IOPS for reads and 2,000 for writes for both Micron and SanDisk's kit.
The SanDisk 1 TB microSD card will launch at $450 in April, or $200 for a 512 GB version.
The Secure Digital 3.01 specification defines a maximum capacity of 2 TB (2048 GB) for SDXC and microSDXC cards. The Secure Digital 7.0 specification introduced the Secure Digital Ultra Capacity (SDUC) format with a maximum capacity of 128 TB.

An SLC cache inside the card could help it hit 1 GB/s or even all the way up to 3 GB/s if they add that in a future revision of SD Express. But that's not going to work if you are filming raw video with the intention of entirely filling the card in one go.
If this is a use case that matters, then there could be a market for a post-NAND technology put into a microSD card. Or there will be renewed attention on solving the limitations that NAND has, although overcoming them is another story.
