OCZ Vertex 4 256GB SSD Review


The Vertex 4 is the first SSD from OCZ to ship without the popular SandForce 2281 controller, opting instead for a fresh set of silicon from recently-acquired Indilinx. Despite some issues with write amplification, OCZ's original implementation of the Everest controller in their Octane SSD proved to be quite formidable. The Everest 2-equipped Vertex 4 delivers on the amazing sequential and random write performance promised by Everest 2, with none of the write amplification drawbacks of the previous controller. 



OCZ Vertex 4 SATA III 2.5" SSD


As the fourth generation of the legendary Vertex family, the Vertex 4 Series pushes storage performance to the max and redefines the modern day computing experience. Vertex 4 SSDs are innovatively engineered to deliver industry-leading file transfer rates and superior system responsiveness, all while providing a more durable, reliable, and energy efficient storage solution compared to traditional hard drives. Designed to take full advantage of the SATA III interface, the Vertex 4 unleashes ultimate productivity, gaming, and multimedia applications.

The "Indilinx Infused" Vertex 4 shares its box with a minimal number of items. OCZ kindly includes a 3.5" to 2.5" adapter, along with mounting screws, a manual and an OCZ sticker. There's good reason to be pumped about the industry-leading 5 year warranty, but we would have liked to see a set of cables.
