New Drive, New Controller
Powered by Indilinx Everest 2
OCZ’s Vertex lineup of SSDs are some of the fastest around and with the Vertex 3 already being one of the older high-end consumer-grade SSDs around at the moment, the company is upping and refreshing their offerings with their newest Vertex 4 SSDs.
The new Vertex 4 SSDs are significantly different from the Vertex 3 drives it replaces, mostly because OCZ has made the switch from the very popular SandForce SF-2281 controller to a brand-new Indilinx Everest 2 controller. Indilinx is a South Korean company specializing in SSD controllers and firmware and if the name Indilinx sounds familiar to you, this because OCZ acquired Indilinx back in early 2011. Also, prior to SandForce controllers, Indilinx made pretty decent performance controllers in the earlier enthusiast SSD drives that we became fond of.
The dual-core ARM-powered Indilinx Everest 2 controller is actually highly similar to its predecessor and as Anandtech discovered, it is in fact based on a Marvell controller, quite possibly the newer Marvell 88SS9187. What we do know, however, is that the controller on the Vertex 4 runs at significantly higher clock speeds compared to its predecessor - 400MHz as opposed to 333MHz. It also has 1GB of onboard DDR3-800 DRAM for prefetching read requests. As for the memory chips, the Vertex uses 25nm synchronous MLC NAND memory chips from Intel.
Vertex is OCZ’s flagship lineup of drives and as the latest iteration of the Vertex line, the Vertex 4 features all the things you’d expect from a high-end consumer-grade SSD. Apart from the new Indilinx Everest 2 controller, it also uses the latest SATA 6Gbps interface for the quickest possible transfers. The Vertex 4 will be available in 64GB, 128GB, 256GB and 512GB capacities. For the purpose of this review, we'll be evaluating the 256GB edition.
