OCZ Vertex 4 256GB SSD Review w/1.5 Performance Update @ Real World Labs
 

As some of you already know, at the heart of the Vertex 4 is an “Indilinx Infused” SSD flash processor called the Everest II. This dual core ARM processor is based on Marvell silicon and “Infused” with OCZ’s own Indilinx proprietary firmware. This is an entirely new concept than was the case with OCZ’s previous flagship Vertex 3. The Vertex 3 was an LSI SandForce based SSD which was powered by firmware written by SandForce. Because the Vertex 4’s Everest II SSD flash processor is powered by OCZ’s own Indilinx firmware, OCZ themselves can choose to improve upon the firmware as often as they see fit, which is something the end user can really benefit from.
