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.

These will be useful for taking long videos/recording audio and/or storing music/videos. Not much real use for taking pictures. Sure, it's "nice" to have a giant card that you don't ever have to replace. Right up to the point where it dies. Losing all of the pictures you've taken over the last year or two isn't cool. Whereas, if you have a smaller card, you're forced to think about more permanent storage. Another option is to just keep buying bunches of cards, which is much better than one single giant card. I nearly lost an immense number of pictures to that very issue. Thankfully, I was still able to read from the card. It just wouldn't let me write to it. The lock switch wasn't on, etc. I did a bit of research into what the best kind of card is for a camera. Professionals use smaller cards, especially for event shooting, like weddings. That way, if you lose the data on one card, you're not totally screwed.

It might be cool, if in future there is a "parallel" write capability on these huge cards.
E.g. perhaps look like 4 devices and have a software raid.
Any one with knowledge comment on this possiblity of graceful degredation, vs complete failure?
