OCZ Vertex 4 128GB review

1. Features

Last year OCZ Technology acquired SSD controller maker Indilinx. Some months later the company launched its first post-acquisition SSD based on Indilinx silicon, the Octane series. Currently OCZ is offering the Vertex 4, an SSD based on its Indilinx Everest 2 silicon.

With the Vertex 4, OCZ is releasing an SSD without a SandForce controller inside, unveiling that the future for the company is Indilinx.

We expect to se the Vertex 4 to perform better than the OCtane. Although they both use 25nm IMFT MLC NAND, their firmware is different, with minimal shared code between the two series. We also expect the Vertex 4 to offer high random write performance regardless of the nature of the data (compressible or incompressible), as the company promises.

The Vertex 4 is available in capacities of 128GB, 256GB and 512GB. MSRP is competitive with other 6Gbps drives on the market today. You'll have to spend $130 for the 128GB version, $220 for 256GB and $580 for 512GB.

OCZ is also offering an 64GB version of the drive that can be used as a cache drive along with your HDD. This one retails online for $80.

The Vertex 4 series is backed by a 5-year warranty.

We have in our labs the Vertex 4 SSD 128GB (#VTX4-25SAT3-128G), which promises to offer sequential reading / writing speeds of up to 550MB/s / 420MB/s, along with impressive random read/write performance, as you see in the following table.


Performance 64 GB 128 GB 256 GB 512 GB
Sequential Reads1 460 MB/s 550 MB/s 550 MB/s 550 MB/s
