OCZ Vertex 4 128GB review
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|
|Sequential Writes1||220 MB/s||420 MB/s||465 MB/s||475 MB/s|
|Random 4k Read IOPS2||70,000 IOPS||90,000 IOPS||90,000 IOPS||95,000 IOPS|
|Random 4k Write IOPS2||50,000 IOPS||85,000 IOPS||85,000 IOPS||85,000 IOPS|
|Maximum IOPS3||85,000 IOPS||120,000 IOPS||120,000 IOPS||120,000 IOPS|
|1. Maximum sequential speeds are determined using ATTO,
2. Small file I/O performance is measured using IOMeter 2010
3. Maximum I/O performance is measured using IOMeter 2010, 512 bytes Random
