2013 Samsung SSD Global Summit - Samsung always likes to talk about the large amount of Samsung components in their SSD products. Off to the side at the show we found a dissected 840. Surprisingly, there aren't too many components needed to build an 840, but I wouldn't want to solder everything together by hand!
Samsung manufactures all of the core components, PCB, DRAM, NAND and more than likely several of the small surface mount components as well.
This is the first time we've seen a SSD apart out in this manner. While not exactly news worthy, it is interesting to see for the first time.
