Two companies have announced 1 terabyte microSDXC cards [theregister.co.uk] 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 [wikipedia.org] 3.01 specification defines a maximum capacity of 2 TB (2048 GB) for SDXC and microSDXC cards. The Secure Digital 7.0 specification introduced [soylentnews.org] the Secure Digital Ultra Capacity (SDUC) format with a maximum capacity of 128 TB.
