Crucial 256GB m4 SSD
Overclockers Approved Award
"While the M4 doesn’t compete with the OCZ Vertex 3 in terms of write speed, its read performance is on par. Given the reliability issues that some drives built around SandForce controllers are experiencing, the M4 looks like a more robust alternative that still delivers excellent performance. It lives up to, and in some cases exceeds, the claimed read and write speeds. In addition, the quite attractive pricing in the US makes this one to consider carefully when SSD-shopping. While other sizes are also available, remember that performance is not necessarily the same, and would be expected to be slightly lower for the smaller drives. For these reasons, I’m happy to label this as 'Overclockers Approved' ". Full review

Crucial 128GB m4 SSD
Bang For Buck Award
"The m4 is definitely a rival to the abundance of SandForce driven SSDs on the market, that are tried and tested, and we hope that by looking at the 128GB model, it gives a clear understanding of why you don’t need to spend the extra money to get the same results, in certain circumstances, but as with any purchase, it’s all down to personal preference and what’s the right product for you."
