Our preview of the OCZ Vertex 460 SSD

Introduction

Early November OCZ upgraded its Vector SSDs with a new generation firmware and 19nm Toshiba flash memory, releasing the Vector 150. Today OCZ's affordable series of SSDs received a similar upgrade. The new Vertex 460 is replacing the Vertex 450 with the same formula as the 150: new flash, slightly faster and more affordable.

The new Vertex 460 uses the Indilinx Barefoot 3 M10 controller like the 450. It's identical to the Barefoot 3 M00 in the Vector and Vector 150 SSDs, but has a lower clock frequency. The main difference between the Vertex 450 and Vertex 460 is the switch from Micron 20nm Onfi MLC NAND flash memory to Toshiba 19nm MLC ToggleFlash.

The 19nm flash is a bit cheaper, but also slower. To compensate for that OCZ applies overprovisioning. Whereas the Vertex 450 is available in 128GB, 256GB and 512GB capacities, the new Vertex 460 comes in 120GB, 240GB and 480GB. The new SSDs are at least as affordable as their predecessors.

The graphic below shows how OCZ positions the Vertex 460 compared to the more deluxe Vector 150. Especially the 120GB model is significantly faster than its predecessor. Overall, the sustained performance level has increased, which should be reflected in our continuous activity test.

The performance is very close to that of the Vector 150, but the Vertex 460 comes with three years of warranty for a total of 21 TB of writing. For the Vector 150 that's five years and 89 terabytes. It wouldn't surprise us if the Vertex 460 is capable of the same, considering it has the same type of flash.
