Why are these two different SLC SSD so different in prices...

When their statistics are so similar?

  1. Don't take the Agility, it's slow. Only the Vertex is fast. Have a look at serious benchmarks: the figures you've got don't tell real performance.

    (For instance, Agility's write latency on small files is very bad, and this hampers real performance)
