Is it possible to use a ~16GB Sd card, permanently inserted, as a boot drive and use the two internals (on the server model) for other tasks? What would the speed be like compared to a 7200 rpm drive?
SDs are not made to be booted off in everyday life.
Looks like you can:

But it's useful just for disaster recovery.

Are you aware that this slot supports SDXC (SD 3.0), that means 2TB drive size support and 300MB/s (R/W).
How does that make feel your Intel SATA MLC SSD drive now? Yes, feels like a big old dinosaur.
There is absolute no reason why we should not expect cheap multi channel & wear-leveling drives SDXC very soon on the market. It´s a real big consumer market cause of all the video and photo cam´s.
I´m sure there is a reason why Apple put this drives in all of it´s new boxes. And the placement of this slot at the back-side of the mac mini tells me that this slot is not planned for every day digital camera card usage.
