We went ahead and tested the Vertex 2 and X25-M drives using Intel's ICH10R controller in AHCI mode, since neither SATA-based SSD is able to saturate the interface's peak throughput. In a more business-oriented environment, you might use an Intel- or LSI-based SAS/SATA controller to enable higher port counts. Here, though, we're concerning ourselves with performance typical on a desktop platform.
