SanDisk (Western Digital) has announced a 400 GB MicroSD card for $250:
In 2015, SanDisk released the world's first 200GB microSDXC storage media using TLC flash technology. Today the company announced a successor, the Ultra MicroSDXC UHS-I, which doubles capacity to a massive 400GB housed within a card roughly the size of your finger nail.
This form factor is now the de facto standard for several classes of devices that span a wide range of product types. Most modern cell phones and tablets have standardized on microSD, and the technology has also penetrated other devices, such as drones and game consoles.
This new 400GB model can hold up to 40 hours of Full HD video and has a transfer speed of up to 100 MBps. That comes out to transferring up to 1,200 photos per minute. The card also meets the A1 App Performance Class specification built by the SD Association to ensure high random performance. The specification insists that products carrying the logo can meet or exceed 1,500 random read IOPS and 500 random write IOPS for quick loading of mobile optimized applications.
Time to update your sneakernet bandwidth calculations with this and a 787 Dreamliner.

400GB? And 200GB before that? What the heck is wrong with these idiots at SanDisk? Don't they know that these cards are always supposed to have capacities that are a power of 2?

Those are powers of 2. In particular 200 = 27.643856189774724 and 400 = 28.643856189774724.

AFAIK these were based on 256GB and (I assume) 512GB chips.
Alternative theory is they were 128+64+8 and 256+128+16GB chips internally.
Third alternative: The actual chips are being developed for base 10 storage marketing and these values are closest.

Fourth possibility: FLASH cells develop errors, so you reserve 20% capacity on your 256GB assembly and market it as 200GB
