OCZ Vertex 3.20 20nm 240GB SSD Review

Honey I Shrunk The Vertex 3 (Again)

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.

The Vertex 3 was originally the flagship drive from OCZ at its inception but that honor now belongs to the Vector series. Still, one cannot scoff at the robust specifications of 500MB/s reads and 520MB/s writes. This is still a very fast drive although how it compares to the Vector and other competitors we’ll let you see for yourself on the following pages.

    The exterior design is almost dead on the original Vertex 3 save for the “.20” appended to the name. Black and silver is still the color scheme of choice.

    Included in the packaging is a multilingual brochure with installation instructions and warranty information along with the latest sticker design professing fondness for OCZ SSD products. Everyone loves stickers.
