With the new MBP of the late 08 manufacture line (i.e the ones with the Express card slot) there should be a nice amount of Front side bus band width 1067MHZ not sure if the CPUs will be used or not. Either way they all have E-sata local HDD with 3GB band width which less operational used band width will be enough to match the Express lane of 2.5 of the Express card slot.
The internal drive is indeed a SATA unit - interface capable of up to 3Gbps. Unfortunately, no mobile 2.5" HDDs (nor SSDs) are available to maximize that bandwidth. But yes, a fast internal HDD is a good idea. Currently the fastest HDDs on the market is the Seagate 320GB 7200rpm drive. The 5400rpm 500GB drives are close in terms of read speed, but slower for seek and write times. There are SSDs available that are a lot faster for reads, but none really perform any better for writes at the moment.
It's possible to sustain writes out via FW800 of about 75~80MB/s if the firewire drive can handle it. And that's just as good, if not better, than most internal options at the moment.
A hacker option that may work (and I may try it soon); is to remove the internal optical drive and pipe the SATA port out. It won't be a full functionality eSATA port, but I bet I can still connect an eSATA RAID to it just fine.
