I have bad news -- the SD card reader on both the new and old Chromebook Pixel is hooked up over USB2 (i.e. max 20MB/sec transfer rate). There is no internal expansion via msata/pcie. And the SSD is soldered down.

Would it be worth putting a large SD card on it, and using a portion of the internal storage as high speed cache?

I guess so. The question is whether it's worth spending $1k on a laptop with such a restriction, vs. just buying a different one for about the same price that's actually expandable.
