Useful for photographers maybe? The camera I play with these days is pretty run of the mill, 20 Megapixel sensor. Storing Raw images as well as .jpgs, coupled with use of burst mode, exposure bracketing, and all these good modern things, a 64GB card fills surprisingly quickly.
Even more so for video. Video is not really something I do, but istr that 1TB is only about 2-3 hours of uncompressed 4k.
That said, even though the cost per bit is probably on a par with smaller cards, I’ll not be buying one til the price drops an awful lot.
