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.

Neither my phone nor tablets can see anything more than 30 gigs, so anything more is wasted.

It could be highly useful for small form factor computers, robots, and all kinds of video cameras including ones mounted on drones. That's why the speed is mentioned prominently. There is a need for SD and microSD storage to have fast enough write performance to store 4K, 8K, 360-degree video, or high framerate 720p/1080p (the GoPro Hero4 Black for example can record 1440p at 80 FPS, 1080p at 120 FPS, and 720p at 240 FPS).
