Dual boot XP and Vista - disk setup?

[fishboy]

Hi,
I'd like to install as above on a new build and have 3 x 500Gb HDDs to play with, so whats the best way to install these (apart from XP first)? I'm thinking either..

XP on HDD1, Vista on HDD2 and data etc. on HDD3. Possibly with XP swap files on HDD2 and Vista ones on HDD1 but is it worth bothering with the swap files on separate physical drives?

HDD1 & 2 in RAID 0 mirror with separate partitions for the two OSs and HDD3 for data.

Any suggestions? Probably should have bought 4 HDDs and gone for RAID10..

Cheers, Andy.

Cheers both, current thought is to use 2 disks in RAID 0 with three partitions - one each for XP and Vista with the third to act as a primary data drive. Thinking I could then use the third HDD as a back up for the data drive. Will need to investigate some backup software then I can ask to back up this data when I shutdown or something.

Thanks again, Andy.
