Image single SATA drive onto a RAID array?

Hi,

I've currently got XP installed on single, massive C: partition which takes up my entire drive - it's 500GB. I have an Asus P5B Deluxe mobo, which can support SATA RAID, so I want to try going to RAID-0. Not sure how to best do it... can I image my existing installation and then build my new RAID array with two new harddrives and then deploy the image onto them to be my C: system volume. Or I'm stuck with doing a full re-install of the OS and everything again to get my OS onto the RAID array?

Not really sure what I'm doing, any help and tips much appreciated - haven't ever setup RAID before.

seis.

RAID0? Don't do it. Bad idea. Use 2 distinct drives instead.

That said, if you absolutely must (why??) snag a USB drive, Ghost or Acronis DriveImage to that drive, then restore to your RAID0 (bad idea) drive.

Sorry, I wasn't totally clear. I'm thinking I will buy 2 distinct drives to setup a RAID-0 array, but I wondered if it would be possible to restore my existing single drive image to the new RAID-0 drive... that should dramatically improve my disk I/0 no?

Most likely, no, it will not improve your disk I/O. RAID 0 has minimal improvement for a standard desktop configuration. Also, when you restore from a previous install, it will not have the RAID controller drivers loaded, so it won't functional properly, if at all. The best thing to do is reformat / reinstall for moving to a RAID configuration. You can slipstream SP2 & drivers, but you will still have to reinstall programs.

EDIT: RAID 0 might be useful in some things, but I'd never recommend it for a primary disk. I prefer to have a single small disk for boot, RAID 0 for games, temp, and scratch, and RAID 5 for storage.

If you can enable the RAID controller, then boot into WinXP (still attached to the non-RAID adapter) so WinXP can do a PnP, XP will catch the new hardware, install the driver, and you'll be fine from there.

Right. That's what I replied to.

Not really. And your reliability will nosedive - lose one disk, lose the entire volume - bad idea. Don't do it.

Ok, thanks for the info guys. Maybe I will just forget about it... my system is pretty quick and I figured I could get a little more speed from what I figure is the biggest bottleneck, my harddrive. But sounds like it's just not worth it.
