Making an SSD has to be pretty easy if you're a memory manufacturer, right? Call up a few of your suppliers, get some of those sought-after NAND flash memory chips, slap 'em on a small PCB with a well-respected processor - SandForce, Intel, Toshiba and Marvell models come to mind - route it all to a SATA interface and enclose in a 2.5in aluminium shell. Job done.
