Disk platter speed and density are the primary forces in actual interface speed. The fastest SATA disks I've seen so far do around 95MB/s, well lower than the 150MB/s that SATA150 can give. The advantage to SATA300 (and SATA600 when/if it comes out) are: 1. faster cache speed for burst transfers 2. better scaling for port multipliers (but most just use SAS for this anyways) 3. more profits for drive makers who convince you that faster is inherently better.
