Our Summary and Conclusion
Performance Summary: Both the Corsair Force GT 240GB drive and Crucial M4 with its v009 firmware exhibited excellent performance throughout out battery of tests. Overall, the SandForce-based Corsair drive proved to be a somewhat better performer, especially in terms of writes. But the Crucial drive offered more consistent performance with all data types, thanks to the characteristics of its Marvell-built controller, which handles highly compressible and non-compressible data similarly.
As of this writing, the Corsair Force GT 240GB could be found for about $410 on-line; the Crucial M4 256GB drive is going for about $380. At those prices, the Corsair Force GT 240GB model costs about $1.71 per GB and the Crucial M4 about $1.48 per GB. Looking back at performance, the somewhat higher cost of the Corsair drive is justifiable considering its better overall benchmark results. In comparison to similarly configured SandForce-based drives, the Corsair Force GT is also competitive. When compared to the OCZ Vertex 3 MaxIOPS drive, for example, the Force GT offered similar or better performance (although only slightly) in all of our tests, but the OCZ drive with a similar capacity is currently setting for about $479.
All things considered, it's clear that the Corsair Force GT 240GB drive is worthy of an Editor's Choice award. The drive offers killer performance at a very competitive price. Crucial should also be commended for offering a free, sizable performance boost to owners of the M4. The drive may not be as fast as SandForce-based alternatives, but the M4 is a good product nonetheless and worthy of consideration, thanks to its lower cost-per-GB and consistent performance.
