The SATA 3Gb SSD's are actually slower when using the Marvell's SATA-6Gb controller at least according to this article by BenchmarkReviews

Marvell vs ICH10 Conclusion

Consumers don't like to trouble themselves with the technical minutiae that interests enthusiasts. But it's the little things that make all of the difference; most especially in regard to this Marvell SATA 6G SSD Performance vs Intel ICH10 article. For example, most consumers don't realize that the SATA controller they connect their storage device to actually rely on a portion of system memory to create a virtual RAM-drive buffer. In many cases, the Intel driver for the ICH9/10 Southbridge reserves a memory space for cache transactions. These memory allocations appear in the form of Cache Line Size and Prefetchable Memory Base, and enable faster transaction throughput. But Intel is not alone.

Marvell's SE91XX driver actually follows along the same principals, but with a lack of refinement the differences are quite clear. Benchmark Reviews has exposed a terrible flaw in the design, and only time will tell if SSD performance on the Marvell SATA 6Gb/s controller chips will improve to meet the level Intel's ICH10 Southbridge can deliver. Until then it appears that the marketing hype is simply that, and hopefully Benchmark Reviews has helped you avoid a costly mistake.
