Some of the new SSDs have hit the limit. They do not reach full speed unless they are connected to a SATA 6 Gbps controller, something Intel is not going to put on their motherboard until 2011. There is also an issue with where the SATA controller is in the system architecture. There is a throughput limitation on disk performance on older machines because they only use two PCI-x lanes. Putting more than two SSDs can run up against the limit. The mini is not affected because it only has two SATA connectors and you would run up against the SATA bus limit before hitting the north bridge limit.
