It’s often asked “why doesn’t Windows Home Server use RAID?”. The simplest answer is RAID sucks as the basis for a consumer storage product. or “Windows Home Server is a consumer product that provides an amazingly powerful yet super-simple to use solution to centralizing a mutli-PC household’s storage. Windows Home Server includes a new, revolutionary storage technology we call “Windows Home Server Drive Extender” that kicks RAID’s butt.” or “Windows Home Server does provide an amazingly powerful solution for the storage of a family’s digital stuff. This solution is exposed to users in the household as Windows Home Server Shared Folders and to the person who sets up the home server as Windows Home Server Storage.“
For the geeks reading this, the underlying technology in use here is SMB/CIFS. Windows Home Server Remote Access makes it easy to access shared folders from outside the home using a standard web browser as well.
