After the Vertex 460 with 120 Gigabyte capacity we're now having a look at the Vertex 460 with 240 Gigabyte. Usually solid state drives with 240 Gigabyte capacity are quicker than 120 Gigabyte models. In this case we're curious to see what the differences between these to drives will be.
Specifications / Delivery
With the entire supply chain in their back OCZ it can now be expected from the company 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 logic, that could be found with the Vertex 450 already. Apparently, since OCZ is now using latest Toshiba NAND there were some changes to the firmware necessary, in order to keep performance and endurance up as high as possible.
With the Vertex 460 you get OCZ's Barefoot 3 M10
controller which the company develops inhouse. 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 improving performance. When it
comes to the NAND interface, OCZ uses and eight channel ONFI/Toggle interface.
