Does anyone have any experience with doing this? Most importantly, does the latest Power Kernel have RAID-support?
AFAIK (and I could be very, VERY, wrong) RAIDing works only with the same device and capacity i.e. a 64gb Plextor with another 64gb Plextor SSD, not a 32GB eMMC and a 16GB mSD (or even 32 for that matter)...

That being said it should be possible to spread loads by other means, just not RAIDing; I saw a kernel module (this was a couple of years ago) that simulated a Flash-Based device and every byte written to an odd-numbered sector was sent to one HDD and vice-versa, probably too CPU-intensive for N900 but who knows...
