OCZ Agility 4 256 SSD Review – 57p per GB!

OCZ have the leading Solid State drive right now with their Vertex 4. There is no doubt that the LSi Sandforce 2281 controller has the edge in pure compressible throughput, however the Indilinx Everest 2 delivers excellent balanced results with both compressible and incompressible data streams.

We have already published several positive reviews of the Vertex 4 128GB and 512GB and it has been interesting today to ascertain overall performance from the value focused Agility 4.

OCZ have managed to cut the dropping prices even further by utilising less expensive asynchronous Micron NAND flash.

There is no question that the Agility 4 isn’t as fast as the Vertex 4, but in the ‘real world’ we would be hard pressed to notice any difference. While our reviews primarily focus on pure technical data, in everyday situations there is often only 1 or 2 seconds difference between the Vertex 4 and Agility 4.

You can buy from ARIA for only £146.34 inc vat, which works out at around 57 pence per GB. This can surely be classed as one of the finest high capacity Solid State bargains of 2012.

That said, the biggest challenge OCZ face is that their Vertex 4 256GB is available for only £39 more now, at around £185 inc vat. If you need ultimate performance then the £39 is well spent, however for most of us, the Agility 4 is more than enough.

On a pure value for money basis via ARIA, the Vertex 4 costs 72p per GB, and the Agility 4 costs 57p per GB.


  • bargain price point for the capacity.
  • excellent storage and boot drive.
  • IOPS is strong.
  • good performance with incompressible and compressible data.


  • Vertex 4 is faster and only £39 more expensive.

Kitguru says: The Vertex 4 is competitively priced but the Agility drops the cost per GB to under 60p. Fantastic!
