you can order them from Dell, but unfortunately the price seems to change with whomever you speak with. The runcore 16gb is slow, I wouldnt waste money on it. If you just need a 16gb, look at the Supertalent for ~$50 shipped. The Stec is faster in some ways and slower in others (read is slower, write is faster), but I am happy with my Supertalent and you cant bet the price right now. When you get to the 32gb range, the Runcore is faster than the stec, but if you need it soon you may have a hard time or pay way more than its worth.
