I am interested in if any one has succeeded in making a pair of portable laptop drives in cases striped using Disk Utility?

In an ideal world, I would like to use a pair of 60GB 7,200 laptop drives, bridged FW 400. It would stand to reason that I would most likely have to scale down the 800 port to match the throuput of the 400 for a reliable stripe. Pardon my ignorance, but I am assuming you can not just use the two on a hub plugged into a single FW800 or 400 port and still be able to stripe them.

The main thing is that I would like to see a significant gain in using that array as my primary scratch disk while in PS CS2. I figure dual 60's would keep it cheap and large enough for most batch conversions. Speed thing.

Even if I do this stripe between a pair of Lacie portable DT drives at home, what would be the gains in using that as my primary scratch disk using Photoshop?

What in the world does this have to do with Powerbooks?

Pair of Hitachi 7K60's as a hot pluggable RAID 0 stripe for a powerbook used as a primary scratch disk in Photoshop.

Now that we've got past that one, how about some ideas and experiences, any percieved issues? Gains?

Just because you want to use a RAID with a Powerbook doesn't make this a Powerbook specific topic. You'd probably get a better answer in a software forum about Photoshop with people who are always looking for faster rendering and operation in PS.

While I can see your point, isn't it probable that people who might have previously tried something like this are *most* likely to br browsing the Powerbook forum?

You're exactly right. No part of this question is PowerBook-specific.

Off to Peripherals...

1) "Scale down" the port? You can't do that. It works at the speed of the device connected.
2) That is an incorrect assumption. Disk Utility allows you to make an array from any drives, regardless of how they are connected.

For most of the disk, a single 7200RPM 100GB 2.5" drive can saturate (the practical bandwidth of) FW400... once you're going to use two disks you'd need an external power adapter, at which point you might as well go to a 3.5" Raptor for better seek times and about the same throughput.
