Vertex 4 is an SSD that we know well, we have tested in its 512 GB, but with a somewhat too new firmware, which sometimes penalized. So far, we test again the Vertex 4 in declination 256 GB, but this time the firmware is successful and wants is stamped 1.5. See the results of the latter in this article.
