While the SDUC (Secure Digital Ultra Capacity) format of the 7.0 SD specification permits up to 128TB, no such drives exist on the market. The reason why is fairly simple. Compared to something like an M.2 2280 size NVMe drive, SD cards are seriously restricted on space, so multiple NAND flash chips can’t be attached to increase the storage capacity.

SD cards aren’t known for being particularly fast, though, and the 4TB model will be different, using a UHS-I (Ultra High Speed) interface and having a Class 10 speed rating—that’s good for a minimum transfer rate of 10 MB/s and an absolute maximum of 104 MB/s. It will also sport a V30 Video Speed Class, which means it will have a minimum sequential write speed of 30 MB/s.
While that’s nowhere near a typical NVMe drive, it should be fine for 4K or even 8K video recording with a digital camera. I personally wouldn’t use it for gaming on a handheld device (not least because I’ve got an ROG Allywith a decent SSD) but if you need lots of storage and don’t care about performance, it should boost the capacity of such a device quite nicely.

Assuming, of course, you can afford it. Western Digital hasn’t announced any prices for the forthcoming 4TB card but given that a 1TB SanDisk Extreme Pro model, with the same interface, is around$140 on Amazon, it’s not hard to imagine just how expensive something four times larger is going to be.
It’s kind of mind boggling that something with 4TB of storage can be made so small. Modern chip engineering is pretty incredible stuff. Now if only it could be made so that it’s impossible to lose an SD card in a drawer full of junk.
