OCZ is now offering a new 20 nanometer (nm) NAND flash version of its Vertex 3 SSD Series.

The new Vertex 3.20 SSD is a 2.5-inch, 6 Gbps SATA III-based Multi-Level Cell (MLC) drive that implements the feature-set of the Vertex 3 Series but is built around smaller NAND flash process geometry.

The Vertex 3.20 SSD will be available in 120 GB and 240 GB storage capacities, with 480 GB capacities to follow soon.

Utilizing the LSI SandForce SF-2200 processor, the Vertex 3.20 SSD delivers high performance of synchronous 20 nm NAND flash supporting read bandwidth up to 550 MB/s, write bandwidth up to 520 MB/s, random read performance up to 35,000 input/output operations per second (IOPS), and random write performance up to 65,000 IOPS. It is also optimized to provide excellent endurance and reliability coupled with power efficiency.

The Vertex 3.20 SSD is supported by a 3-year warranty.
