After my disappointing experience with a NAS I tested a few weeks ago, I was really looking forward to evaluating this unit. To recap, a network attached storage (NAS) device is a shared disk drive that uses your internal network, or in some cases the internet to share data with multiple computers. It’s a great place to store backups, large media files (such as for home theater systems), archived multimedia projects, or anything else that requires larger than average amounts of storage space.
