Correct, Deneva is the enterprise product. Basically, identical to the consumer line (probably equiv to Vertex), marketed to OEMs instead of consumers (much like how Micron SSDs are the same thing as Crucial SSDs, just marketed differently and have a different level of support)
We used to use their Intrepid SSDs at work. They were the equivalent of the Onyx line. I could load Intrepid firmware to an Onyx SSD, and Onyx firmware to an Intrepid SSD. inside the case, they looked identical.
