OCZ Vertex 4 256 GB Solid State Drive Review
12 November 2012
Summary: We can see from our tests that the OCZ Vertex 4 and Kingston HyperX 3K have strengths and weaknesses in different areas. This makes it quite difficult to make clear-cut judgments about which one performs best.
Excerpt: We've looked at many SSDs here, and they've mostly been implementations of the popular SandForce NAND controller. While this isn't a bad thing, as the performance offered by those drives have been good, it's good to see more competition in the growing SSD market.
OCZ Vertex 4 256 GB Solid State Hard Drive SSD Review
4 October 2012
Summary: The Vertex 4 is a departure from OCZ's tried and true model of using third party controllers and firmware for its SSDs. Taking control of the firmware with the Vertex 4 gives OCZ the ability to tune the SSDs for speed and performance at lower queue depths and optimize for low latency.
Conclusion: After years of begging, OCZ has finally delivered much of what we've wanted in an SSD: low write amplification and very good random/sequential write performance. It could use a more aggressive real-time garbage collection algorithm but running an OS with TRIM, that's mostly picking nits.
Excerpt: Many of the OCZ models are revisions and improvements of a previous which is the whole reason for the Roman numeral being displayed in the model name. And in the case of the review sample here today we have the Vertex 4.
Conclusion: I think the issue with our OCZ Vertex 4 256GB is not a lack of a star front and center to lead the play; it is the lack of proper recognition of talent that kept it from shining through in our review today.
Conclusion: TRIM Performance: While SSD's offer many benefits, there are some downsides to using flash memory. One of the biggest issues people run into is performance degradation. Over time, an SSD will run out of fresh blocks and will have to write over data the file system has marked as deleted.
Pros: Available in 64GB, 128GB, 256GB and 512GB capacities, Good sequential read and write speeds, Excellent random read and write performance, Performs equally well with compressible and incompressible data, Indilinx Ndurance 2.0 technology extends life of NAND flash, SATA 6Gb/s interface, Synchronous...
Cons: Requires firmware updates for best performance
Conclusion: We can actually draw several conclusions from this test. First and foremost, this drive is not only fast, but it's consistently fast, which is something that you can't say about many SSD's.
