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: 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: 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.
Conclusion: The main concern is the flash NAND degrade that you get to see. Now, I do a lot of runs on Anvil Endurance test alone and on top of it I do each test 3 times- and with few of them with different data fill on the drive.
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
Summary: Flagship solid state drives from OCZ – Vertex 4 – underwent yet another spec modification caused by the release of the new firmware version 1.5. Therefore, we decided to retest the “updated” Vertex 4 SSDs and try to figure out the reasons behind the notorious performance drop after filling up more...
Summary: The Vertex 4 256GB solid state drive is an impressive unit, and a nice upgrade over the previous generation of Vertex drives. It offers more than you would expect from a consumer class drive, with fast transfer rates, and a 2.5" drive adapter that will make installing the drive in to either a laptop...
Pros: » High performance, » Low cost, » Designed for reliability, » 5 year warranty
