"For small and medium-sized businesses that want to build a shared file system or a personal storage hub, the cost won’t be a burden. […]     Looking at future scalability, NAS's App Center also includes a number of commercial applications to choose from, from the use of Scale-Out or Stackable (iSCSI volume) to increase storage capacity, but also the use of disk migration directly to install onto more powerful models”
