OCZ Vertex 4 SATA 3 SSD Review – Indilinx Infused and Game Changing Performance Results

Our SSD analysis today is going to be on both the 256GB and 512GB versions of the OCZ Vertex 4 SATA 3 SSD and you are going to need to take a seat for this.  We guarantee that there has never been an SSD capable of creating such a stir in the SSD world and will not be at any time in the near future.

In fact, I will guarantee that you will look at solid state drives in an entirely new light by the time you’re finished reading this report. After all, the Vertex 4 is truly the first of its kind.


Each and every SSD received at this site is an exciting event.  I can guarantee that not ten minutes pass between the arrival of an SSD and it being ripped open and hitting the Test Bench.  For me, it is like Christmas as a child and I just have to get it open, see it first hand and than it has to be photographed and tested right then.  The Vertex 4 was no different.

Imagine waiting so long for an SSD to arrive that might be a game changer, receiving the box from UPS and then opening it to find, not one but two Vertex 4 SSDs, one being an incredible 512GB capacity and the other being 256GB.  Can anything get better than this?

Now imagine doing your first PCMark Vantage run with this baby and receiving the lowest Total Point score you have ever received for a SATA 3 SSD.  Not possible right?

Absolutely true story and that happened with, not one, but both Vertex 4 SSDs and I was stunned.  I thought our test bench was wrong.  In the end, I tested both Vertex 4 SSDs in PCMark Vantage on three test systems for a total of about 15 runs. In the end, I moved on to complete our testing regimen and learned something new about SSDs, something that I think you may just appreciate by the end of our report.  The Vertex 4 is a game changer and I am going to show you why.


The Vertex 4 6Gbps SSD is available in sizes of 128, 256 and 512GB capacity which is 7% capacity jump from previous Vertex releases and that is a good thing.  Performance peaks at 535MB/s read and 475MB/s write for the 512GB version with the write performance dropping to 380MB/s for the 256GB model and 200MB/s for the 128GB model.  IOPS are a listed at 95,000 IOPS read and 80,000 IOPS write for the 512GB drive with the other two having 90,000 IOPS read and 80,000 IOPS write.

The Vertex 4 has an industry leading five year warranty, auto encryption and AES 256-Bit support, advanced ECC engine and OCZs own proprietary Ndurance 2.0 Technology which is an advanced NAND flash management suite to increase durability and reliability.  Simply, it reduces write amplification without compression which increases the longevity of your memory.


The exterior casing of the Vertex 4 is of black moulded plastic with a metal base plate secured by four screws, one covered with a security patch that says, “Warranty Void if Removed’.

The printed circuit board (PCB) of the 512GB version contains the Indilinx IDX400MOO-BC Everest 2 processor, 16 modules of Intel 25nm mlc 32GB synchronous NAND flash memory (29F32B08JCME3), and two modules of Micron DDR3 DRAM cache.  Although total capacity is listed at 512GB, formatting leaves the end user with 477GB of available space.

The PCB of the 256GB version is not shown in favor of getting some nice close ups of the 512GB drive. Both SSDs look exactly the same, given exception to the memory modules which are 16 modules of Intel 25nm mlc 16GB synchronous NAND flash memory (29F16B08CCME3).  The Vertex 4 256GB SSD has a formatted capacity of 238MB
