IIRC the article in The Register said its set up to boot from either SD
card on a USB3 external storage device, so why bother with an SD card on
it since its got two USB3 sockets: just stick an SSD or HDD in one of the
USB3 sockets.

Experience with my Athlon box shows that 4GB RAM allows enough disk
caching to dramatically speed up both C and Java compilations.

I didn't notice quite such a speed up with an older Lenovo R61i (1.4GHz
Core Duo chip and 3GB RAM), so it looks as though disk caching becomes a
significant speed-up factor somewhere between 2 and 4 GB RAM.
