Kioxia Develops Industry's First 2TB microSDXC Memory Card Working Prototypes
Kioxia Corporation, a world leader in memory solutions, today announced the industry's first 2 terabyte (TB) microSDXC memory card working prototypes. Using its innovative BiCS FLASH 3D flash memory and an in-house designed controller, basic functions of the KIOXIA 2 TB microSDXC UHS-I memory card working prototypes were confirmed in the microSDXC standard's maximum density.
As the data recording capacity of smartphones, action cameras, and portable game consoles continues to increase, the need for ultra-high capacity SD memory cards to store all of this data has never been higher. The SD Association's SDXC specification has supported memory cards up to 2 TB for more than a decade—but 2 TB cards have not been successfully manufactured until now.
Designed using the company's proprietary manufacturing technology, the KIOXIA 2 TB card working prototypes are built by stacking sixteen 1 terabit dies of 3D flash memory and achieve a maximum thickness of 0.8 mm at the die mounting area - making them well-suited to high-capacity data recording applications.
Mass production of the KIOXIA 2 TB microSDXC memory cards is scheduled to begin in 2023.

Basically, it goes bad, you are on your own. While SD cards are better but not all of them are made the same and they die.
What on earth can take place a 1Tb on a phone?
idk... most people still use laptops with conventional hard discs, even truck drivers. At least I hope you don't watch them while driving.
The internet isn't always going to be there so I have a lot of music albums in case (and it has come in handy in dead spots).
Also, check out Starlink. You can have usable internet anywhere, any time. $100/mo for service, and $500 for the equipment.
If you wish to discuss side topics... start a thread in the proper section.
With the increasing density, why don't mSD cards have any thermal mitigations? Seems many of the dead and slow cards on the Steam Deck are coming from them overheating.
On my Deck, a 128GB SanDisk 'Nintendo Wii' mSDXC can get so hot you can barely touch it. ...and that's *with* my own modification, trying to address heat.
