Hardware is nice, but software is just as important: ReadyNAS 716 runs on the same ReadyNAS OS 6.x as the rest of the ReadyNAS line of product. For consumers like you and me, this means that nearly all the features available in the professional NAS system from NETGEAR are also available to regular folks with storage devices that are more nimble from a computing point of view, but just as sophisticated when it comes to security, features and relative ease of use.
Before you get too excited and start searching for the ReadyNAS 716 online, you should know that it is a $3000 (give or take) device that is designed for an Enterprise use, so this will be overkill for most people. That said, a small/medium design agency could probably use something like this for their storage needs.
