OCZ had a very good run with SandForce but, if the Vertex 4 is any indication, the company´s future is with Indilinx. Powered by the Indilinx infused Everest 2 controller, the Vertex 4 combines synchronous MLC NAND with a massive cache to deliver some of the best all around performance we´ve seen. With the v1.5 firmware, the drive was able to read at speeds as high as 561 MB/s and write at speeds in excess of 480 MB/s. The Vertex 4 also edged out the SandForce-based SSDs for the top spot in our 4K random write tests, producing more than 82,000 IOPS. Best of all, it performed equally well with compressible and incompressible data and was able to sustain these speeds, even after intensive use.
The Vertex 4 is available now in 64GB, 128GB, 256GB and 512GB capacities. Prices on Amazon currently range from $74 up to $545, with the 256GB version reviewed here going for about $210. At less than $1/GB this is a very good price, especially when you consider that the 240GB Vertex 3 still goes for around $200 and the 256GB Plextor M5S sells for nearly $250.
