The Vertex 460 marks a new chapter in the history of OCZ. Meanwhile Toshiba has bought OCZ and the company now operates under the name OCZ Storage Solutions as a subsidiary of Toshiba. When it comes to the Vertex 460, we have basically a Vertex 450 lying in front of us with the latest NAND flash memory from Toshiba. Other than that the firmware needed to be upgraded an optimized in order to sequeeze maximum performance out of the drive.
Specifications / Delivery
With the entire supply chain backing them up, it can now be expected from OCZ that the Vertex 460 is not only a very quick drive but also features an aggressive price tag. A closer look at the controller reveals that there is the same Barefoot 3 M10, which could be found with the Vertex 450 as well. Apparently, OCZ is now using the latest Toshiba NAND and there were some changes to the firmware necessary in order to keep performance and endurance as high as possible.
With the Vertex 460 you get OCZ's latest Barefoot 3 M10
controller which the company developed in-house. According to the block diagram we
can see that the controller is based on an ARM architecture. Additionally OCZ
optimized the clock generator towards lower power consumption, which they
already did when they released the Vertex 450. In other words
this means, they've lowered the internal clock speeds in order to make the drive
more energy efficient. Furthermore this drive ships with AES 256-bit encryption
as well as an ECC engine which is taking care of error corrections. On the right
hand side of the diagram you can see that OCZ equips the Vertex 460 with an
additional DRAM cache, which in the end helps to improve performance. When it
comes to the NAND interface, OCZ uses an eight channel ONFI/Toggle interface.
