When reading, it caused noticeably slower operation. We are not writing video at 10MBPS, we are running a Linux OS which uses a lot more small block operations (4K or smaller reads/writes).
You might also want to compare the specs for the SanDisk eMMC in the KA1 to the specs for a class 10 uSD card before getting too enthused about the value of any increase in storage speed. From what I see of the part number (SDIN8) and searching on SanDisk's site, as a minimum, it would beat a class 10 uSD card with a minimum 17MB/s read, 90MB/s write (SDIN8DE1) and quite possibly beat a UHS 3 uSD card with a 30MB/s read, 115MB/s write (SDIN8DE2).

I know that eMMC is going to be leaps and bounds beyond any uSD card as they're literally the bottom of the bin in terms of flash performance.
Finally to the other people talking about why it's pointless to have a better SOC, then explain to me how in the hell the chinese folks at dasung are doing the NOOK fast-refresh 1bit mode in what is at least 4 colors but from the video looks like 8 colors. That's what I want, I want page turns to be faster the UI to be snappier as it stands the whole thing is sluggish.
