The fact that we can do parallel reads from an SSD does give more flexibility to DB developers.
It all depends though if you want throughput or latency. If you really really care about latency you should balance the queue depth and probably use it between 16 and 32. The reason is that with higher queues you get more collisions on the same die and then latency suffers. There are read-read, write-read, erase-write and all the other combinations but those three are the interesting ones.
