I have a 2007 MBP with sata150. Currently the drive is a C300 64gb and it's very fast even though read speeds are capped. If I get an expresscard esata adaptor and run my ssd from there will I get faster throughput than with the drive on the internal sata bus, assuming the esata card I get has a good enough controller? From my understanding the mbp's expresscard is connected through pci express at 2.5 gbits. Is this correct? Any old-style MBP users out there with esata and SSD?
