The handiest thing about WHS is the Drive extender feature. Its basically software RAID. You set what folders you want it to duplicate and it makes sure that the folder is duplicated onto another drive. Best thing is, as your storage grows, you just clag in another disk and tell it to add it. Doesnt matter about the capacity of it either. You can also access your files from any pc running internet explorer, as long as it is set up correctly. It offers pnp to do this too, so as long as you have a pnp router, it sets all the port forwarding etc. for you.
