Just when the SD wannabee thought it was winning.

500 MB/s (using PCI Express!)   (B, not b, they say).
Addressing to 2 TB

500 MB/s sounds awesomely fast.
They you look at how long it would take to download 2 TB.
2000/0.5 =3D 4000 seconds =3D 67 minutes!

However, a nice little 64 GB card would download in a mere 2 minutes 10s or=
 so.
