Notebooks w/ RAID?

macemoneta asks: "Are there any notebooks available on the market that support (bootable) RAID (at least two 40GB+ drives as RAID0 and or RAID1)? While the rest of the components in 'desktop replacement' notebooks are quickly getting up to snuff, the hard drives are anemic in performance, capacity and reliability compared to desktops. Being able to use software RAID to create high performance meta devices and high reliability meta devices would really kick notebooks into high gear. Before anyone complains about size, weight, power and heat remember that notebooks have gone from 12 inch screens to 16 inch screens and 486 to P4M in the last few years. Most desktop replacement laptops use the batteries as a UPS, since they usually only last 90 minutes or less anyway."
