Being more familiar with assembly would definitely help. The only time I look at assembly is when I'm using a JTAG debugger, which is not my primary activity.

Our firmware has a lot of ASIC pathways that are only accessible through register reads/writes, and in some circumstances only statuses are available through the registers, so I believe reverse engineering an SSD would be more difficult than it first appears.
