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.
|Model||OCZ Vertex 4 256 Gigabyte|
|Memory||Synchronous NAND Flash|
|Technology||Intel 29 F16B08CCME3|
535 MB/s reading, up to 380 MB/s writing
up to 90'000 IOPS write
up to 85'000 IOPS read
|Accesstime (read)||< 0.1 ms|
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.
