OCZ Vertex 4 256GB Review
28 September 2012
Excerpt: OCZ has typically reserved its Vertex label for the highest-performing SSDs in a given generation—using synchronous NAND, for example, rather than the asynchronous NAND found in its less expensive Agility series. The 256GB Vertex 4 carries on that tradition, with 16 128Gb IMFT 25nm synchronous NAND packages on a board with 512MB of DDR3 DRAM cache and OCZ’s new Indilinx Everest 2 controller.
Pros: Never-before-seen write speeds; new controller.
Summary: OCZ's Vertex 4 delivers impressive performance at a great price. Thanks to the Indilinx Everest 2 controller, the drive claims a leading spot in our performance benchmarks. We see it perform within 1% when compared to the fastest SandForce drives we have in our test group. It is also only 2% slower than the much more expensive Corsair Performance Pro 256 GB, which is the fastest drive we tested so far.
Pros: Very fast, beats Sandforce-driven drives, Great price/performance, SATA 6 Gbps support, Supports TRIM, 5 year warranty, 3.5" adapter included
Cons: Bluescreen issues with 1.4 firmware, Needs SATA 6 Gbps controller to perform best
Summary: Final Thoughts
It was a very bold move by OCZ to go out and purchase Indilinx, thus acquiring the technology behind the Everest 2 platform. This really shows OCZ’s dedication to being one of the top manufacturers of solid state drives. They could have just as easily created another drive based on the SandForce SF-2281 chip and made some changes like 0-provision or a different type of NAND and called it the Vertex 4.
Pros: – Great performance, – 5 year warranty, – No performance drop when dealing with incompressible data, – Constant firmware updates have improved performance
Conclusion: Given what we saw from the first Everest controller in the Octane last year, we weren't sure what to expect and if the Everest 2 would be able to best the SandForce SF-2281 . Those concerns were quickly squelched as the Vertex 4 256GB defeated Kingston's HyperX 3K and Intel's SSD 520 Series in all three of our file copy tests, with the program and game results being particularly impressive.
Conclusion: IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete.
Pros: Industry-leading 5-Year OCZ product warranty support, Unmatched 83,494 4K IOPS performance, Impressive 548/471 MBps read/write transfer speeds, Indilinx Everest 2 processor offers native TRIM support, Automatic AES data encryption, Indilinx Ndurance 2.0 technology extends NAND lifetime, Offered in 64/128/256/512GB storage capacities, Lightweight compact storage solution, Resistant to extreme shock impact, Low power consumption may extend battery life
Conclusion: Performance Summary : The new OCZ Vertex 4 performed very well in the majority of our tests, but there were some obvious strong points that standout. Random reads and writes are where the Vertex 4 really shines, and performance got better as queue depths increased. The drives put up some of the best scores we’ve seen in IOMeter with 100% random access, performance is consistent with both incompressible and highly-compressible data, and in the CrystalDiskMark 4K QD32...
Pros: 5-Year Warranty, Competitive Pricing, Great Random Access Performance
Cons: Relatively Low Sequential Transfers, Not Clearly Faster than Vertex 3
