SBN MBP ExpressCard Questions

Greetings,

As you're all no doubt aware, Apple silently bumped their MacBook Pro lineup to rev B a short time ago. This made it a good buy-in point, and I'm interested. I have a few criteria to meet, one is that I'd prefer to use some of my legacy ExpressCards (specifically the eSATA one) if it was possible. I'm aware this would mean buying the 17" and I'm fine with that.

The question revolves around how Apple has implemented ExpressCard. Have they laid down additional traces to the chipset, and given it the spec 2.5Gbit theoretical throughput, or have they simply stuck a USB back end on it?

With most manufacturers I wouldn't have to ask this question, but Apple likes to do sneaky stuff. If the ExpressCard slot is in USB Mode, then it is limited to 480Mbit/s, and there is no reason to buy the 17", I would opt instead for the 15".


If anybody knows anything about this, I'd love to know. Thanks, Julian

To partly answer my own question...

I located a 17" SBN MBP to dig around in. Did not have an ExpressCard on me so I couldn't test anything fully. However, as this screenshot tells, it looks as though it is a PCIe enabled slot.

I'm unsure what "Long" vs "Short" means, it appears to be a 1x lane. So it should be good for the 2.5Gbps that the specification indicates. If anybody has additional insights, I'm all ears.
