OCZ Technology is no stranger to the computer industry. Founded by enthusiasts, for enthusiasts, the company entered the memory market in 2002. Determined to manufacture the very best memory for overclockers, OCZ quickly established itself as a leader in the industry by breaking speed barriers and maintaining a reputation of quality. Today, OCZ continues to innovate. Along with their line of enthusiast-oriented power supplies, the company offers a wide range of high-performance SSD solutions for the enterprise and consumer markets.

One of the latest additions to OCZ's family of mainstream solid state drives is the Agility 4. Available in capacities ranging from 64GB up to 512GB, this cost-effective alternative to the popular Vertex 4 is based on OCZ's advanced Indilinx Everest 2 controller platform. The Everest 2 is powered by a 400MHz dual-core CPU and offers features like TRIM support, dynamic wear-leveling, AES-256 encryption and Ndurance 2.0 technology, which extends the life of NAND flash well beyond its manufacturer rated specifications. In addition to the Everest 2 controller, the Agility 4 is equipped with asynchronous MLC NAND and an extra large DRAM cache to deliver up to 420MB/s read and 410MB/s write speeds as well as a maximum of 85,000 4KB random write IOPS.

For this review, OCZ sent us the 256GB version of the Agility 4. This SSD comes equipped with 512MB of on-board cache and is capable of delivering up to 420MB/s sequential read and 410MB/s sequential write speeds as well as up to 48,000 random read and 85,000 random write IOPS.
