esata with SSD on older macbook pro

[z125]

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?

Damn, I guess everyone with a ssd also has a newer computer, huh? Anyone get good xbench results on any mbp with esata + ssd? I've seen lots of esata xbenches but they are all with slow drives or the esata has a slow controller etc...
