"OCZ is certainly getting a lot of mileage from the Vertex moniker. First introduced way back in early 2009, it seems a lot longer than just four years ago. They have good reason to perpetuate the name as the Vertex drives have been one of if not the best selling line of SSDs ever. Back in 2011, we first had a look at the Vertex 3 drives featuring the then new SandForce SF-2281 controller. At the time, it featured 25nm -34nm (keep reading!) MLC NAND and set the bar for enthusiast level SSD performance. Fast forward to 2013 and OCZ has quietly released the latest Vertex 3 incarnation with a .20 mantissa tacked on to represent the 20nm MLC NAND contained within. This is somewhat noteworthy in that there was a fuss raised by customers at one point when OCZ decided to move from 34nm to 25nm NAND and not overtly disclose it. Perhaps showing more maturity and proactive thinking from the new OCZ leadership, they've decided to forgo any customer ire by simply re-branding to Vertex 3.20.
What hasn't changed is the controller. It's still the SandForce SF-2281 that the original Vertex 3 came equipped with although this time around LSI is the parent company for the SandForce hardware. It carries the same three year warranty and is offered in 120GB (VTX3-25SAT3-120G.20) and 240GB (VTX3-25SAT3-240G.20) capacities. The 240GB will run you $216.99 and the 120GB Vertex 3.20 solid-state drive is $119.99."
