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.

The current SD specification defines a maximum size of 2 TB for all sizes (SD, miniSD which nobody uses anymore, and microSD).
SanDisk announced a 1 TB SD card in September. This microSD stores 400 GB.
An SD card has about 4.65x the area and 9.77x the volume of a microSD card. It seems that a 2-4 TB SD card could be made today. And flash memory density is going to increase a lot more, especially when we see things like 128-layer QLC 3D NAND hit the market. So the SD Card Association better raise the limit real soon.

I think that miniSD is what happens when two microSD cards mate.
I have an old tobacco tin with a whole bunch of different storage cards in it, SD for my camera, various USB sticks, and several microSD cards.
I recently found a miniSD card in there, and I have no idea how it got there, I'm pretty sure I didn't put it there, and my kids have no idea either, so the only explanation is that some microSD cards mated.

miniSD = 21.5×20.0×1.4 mm
microSD = 15.0×11.0×1.0 mm
miniSD has 2.6x the area and 3.649x the volume.
Apparently nobody bothered to make a miniSDXC so the maximum capacity is 16 GB. That card will be living in your tin, unused, until you put it in a museum.

It's 2GB (I think), so when it gets to 8GB I will release it into the wild, it should be big enough to look after itself by then.
