Today OCZ doesn't only present the 512 Gigabyte version of their new Vertex 4 SSD, there is also a 256 Gigabyte model. According to the specs this one is a little bit slower than its bigger brother but of course it's much cheaper.

Behind the scenes

Basically the Vertex 4 from OCZ is a 256 Gigabyte SSD, which uses an Indilinx IDX400MOO-BC controller and synchronous NAND Flash memory from Intel. These have been manufactured using a 25 nanometer process and the individual chips have 29 F32B08JCME3 written on them. This indicates that the memory cells are specified for 5'000 P/E cycles and the memory itself is connected to the controller via ONFi 2.x standard.

Some readers might have noticed, that OCZ now provides a five year warranty plan with the Vertex 4. For the Vertex 3 and almost all other drives that are available at this time warranty is limited to three years. The reason for this can be found in the so called Ndurance 2.0 Technology, which is an umbrella term of which for example reduced write amplification is part of. At this point OCZ emphasizes that they achieved this without the use of any compression algorithms and therefore there will be no performance drops. Furhtermore there is also support for Advanced Multi-Level ECC, Adaptive NAND Flash Management, Redundant NAND Array Technology and 256 bit AES encryption.

 

Delivery

Included in delivery you find the SSD itself, a cover, a small manual, an adapter to put the SSD into a 3.5 inch slot, screws and a sticker. For the Vertex 4 OCZ make use of their standard box which we know from several other SSDs.
