Vertex 450 is based on 20 nanometer MLC NAND memory and replaces the Vertex 4 line (25-nanometer NAND), and has an OCZ's Indilinx Barefoot controller 3 M10 with lower power consumption (compared with its predecessor), and support for AES-256 encryption. Using 20-nanometer NAND memory makes Vertex 450 cheaper to produce than the previous Vector and Vertex 4 product line, according to the company.

Declared data transfer speed is 540 MB/s for reading and 530 MB/s for writing, with 90,000 IOPS at random writing of 4K data blocks. OCZ Vertex 450 comes with a three-year warranty, but prices have not yet been published.
