If you use a linux/unix livecd, you could use dd to copy the entire drive, including the partition table, to another drive. On an Ubuntu livecd it would be something like this if the RAID-0 is sda and the other drive is sdb.
Code:
sudo dd if=/dev/sda of=/dev/sdb bs=1m
You can only really do this if the drive you're putting it onto is the same or larger size. If it's a bigger drive and you want to use all of the space, once Windows boots you will need to use disk management to resize your partition to the size of the drive.
