Here's a challenge: do you reckon you can fill half-a-terabyte of memory using only a smartphone?
For some people, we're sure, the answer will be along the lines of “hold my beer while I set my camera to HDR mode and snap some selfies”. So the good news is that from February, you'll be able to lay out the readies on a 512 GB microSDXC card from Integral Memory.
At a transfer rate of 80 megabytes per second, you'd need more than an hour and a half to transfer a full card's worth of data; last year's 400 GB monster from SanDisk (no longer the world's biggest little memory card) still has the edge there, claiming a 100 MB/second transfer rate.
Integral's 512GB microSDXC V10, UHS-I U1 card is fast enough to meet V10 (Video speed class 10) for capturing full HD video.
Integral has put up a web page and a Spec sheet (pdf) for it.
Now we can set them up as media hubs for all.

The speed is going to scale up. The more parallel nature of 3D NAND could help that. It's not going to remain the same, and it won't be as bad as hard disk speed scaling.
SanDisk advertises a card [sandisk.com] with up to 275MB/s read, 100MB/s write.
The maximum transfer speed in the standard is higher (312-624 MB/s):
The "video speed classes" recently added to the standard are met if a minimum sequential write speed can be sustained, with 90 MB/s being the highest one (which they claim is sufficient for 8K @ 120 FPS video recording).

At 624 MB/s it will still take 28 hours to read a 64TB disk. 18 days for 1PB.
I think they are going to need to do some sort of multiple serial buses in parallel thing, which is going to mean a whole new standard.
Maybe something like a miniturised old fashioned parallel port, but with each pin acting as an individual high speed serial link.
That said, I can still see a use for these cards, in that you could load your entire media/audio/book libraries on one and have everything available all the time.

Again, 624 MB/s is the *current maximum* in the standard. It is likely to increase in future iterations of the standard, although the speeds will lag behind high performance SSDs.
