Using a Wintec Filemate 48GB Ultra SSD (which seems to be the only express/34 ssd on the market that is internally pcie, not usb). I installed Mac OS X on it using a pre-unibody macbook pro and it boots just fine. Beware, many of the express/34 cards are internally USB, not pci-e x 1, and thus are not good for boot drives.

<strike>Doesn't seem to want to boot on a unibody, but, I haven't had time to investigate</strike>(see follow up post). Also, I'd like to try raid with it.
For those interested, total boot time from press of powerbutton to Finder ready is 27 seconds....x bench report remove txt
