I just bought one of
these and one of
these to go inside it and it is all going swimmingly so far. 500GB of networked, shared storage for all the family photos, movies and music plus a backup of my important data with a single click using
this. And all for a smidgen under £110.
I've also set up FTP access and forwarded the relevant port to allow me to access all of my files across the internet should I require it.
