You can't move ICHXX to a 3-Ware card but you might be able to move to a HW Intel RAID card which would be interesting to find out.
Capacity expansion is supported on ICH10DO and is said to work with ICH10R.
You can move the RAID to a newer ICHXX without any problems and should be able to move it on to the new P55 chips.
Thanks for that. That's reassuring.
Only because I try not to believe everything I hear in forums, can you or someone post a link to where this is documented? By that I mean being able to move an array from ICH9 to ICH10 and the part about capacity expansion.
Thanks, I'd very much appreciate it, it would save me $400 for the RAID card if indeed this is documented (guaranteed by Intel etc).

Email Intel if you can't believe me.

Capacity expansion supported by ICH10DO
Hi Peter. Thanks for the links, I appreciate them. I had googled before I posted the first time but didn't find any authoritative links. Your help has been much appreciated. It's not that I can't believe you. I generally operate under "trust but verify" mode. Been burned before with forum advice (not here). So yeah, the links are very much appreciated. Hope you understand.
FWIW I went with an Areca 1220 card. Reasonable cost, supports 8 drives, native Linux support, and built in httpd for super easy administration. Currently there's only 6TB on it but there's plenty moore room. It's been running 24x7 for over a year now, no issues. I run the Amahi server stack on it which was nice to find since it's free open source and is arguably more powerful them MS Home Server which I wouldn't use if it was free. Amahi installed from a web page with one click after a plain vanilla Fedora install and after that all I had to do was set up shares - again from a web browser and way easier than in Windows. The Windows machines all see the shares fine. The drive cages I used are these hot-swap bays with built in fans http://www.newegg.com/Product/Product.aspx?Item=N82E16817121913. Noisy but reliable. Used an Asus P5BV-M and a 1.8 ghz core-2 duo to power the beast. It does a great job managing a 100GB photo collection, as well as online collaboration tasks and remote virtual desktops (EyeOS), *and* storing a few hundered of my favorite DVDs plus 300GB of lossless and ogg music (for internet streaming when I work remotely or lossless when at home/office).
