Came fully populated and formatted as RAID 1. Setup was fairly easy. Re-formatting for RAID 0 and volume encryption went smoothly. Adding shares, users, and mapping drives also went smoothly. Copying files over was pretty fast. The security seems a bit lax. For example, the initial setup where you supply the NAS unit's admin password could not be done over a secure (HTTPS) connection. Performs well for the most part but it's a bit slow at times on read operations.
