A little over a year OCZ introduced its first in-house designed enterprise SSD series called the Intrepid 3000. What separated the Intrepid from OCZs earlier enterprise SSDs was the fact that it utilized a fully custom OCZ firmware with a Marvell silicon, whereas in the past OCZs enterprise SSDs relied mostly on SandForce controllers with limited customization. Today OCZ is refreshing the lineup by superseding the 3600 with a new 3700 model.
