Well, the past couple of days have been quite a learning experience for me... To begin with, and to show I'm not totally pig headed, I tried the Tom's Hardware approach. Turns out that it doesn't work in multiple ways in my situation. Specifically: - Dynamic Disks aren't supported in XP Home, not even with the hacked files - While Dynamic Disks are supported in Pro and Server, you can't make firewire or USB-2 disks dynamic in any version of windows. There is a registry hack to make firewire disks capable of being made dynamic in Win XP, but there is no such hack for USB-2 IOW, in my situation, these answers aren't an option. So I got coLinux setup with samba and raid. Does it work? Yes. Is it fast enough? Well, that depends on your needs. For just plain copying files around, it's about 1/3 the speed of a native copy for large files between external disks. For playing back music, this is fast enough. For playing back video, it isn't. Which brings me back to the question - would I see any better performance with QEMU and the preliminary version of the accelerator for Windows, or am I just going to have to accept that I need another machine if I want a RAID array? Not that I expect anyone else here has tried this, but figured y'all might find this to be useful info. Of course if someone who's already more familiar with QEMU did want to try this and let me know if it works... :-) Thanks again, Ewan - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
