Looks like this is referring to Windows Vista Ultimate 64 bit. This is possible using Software RAID under Linux [1], you could probably even detach these devices and use a udev/mdadm script to detect them on the fly. This is a hack mind you, and seems strange since RAID is generally used to protect data, rather than for performance reasons. So using removalable USB devices with raid, is possible, but I would not suggest it. http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html
