So far, I'm very pleased with it.
Private and public areas, pretty good security features, sleeps, accessible from offsite via the internet. I have mine set up as an NFS, connected via cable to the wifi router. No issues with any devices on the network locating or accessing the public areas.
Also, it has proprietary backup capabilities that I haven't used yet.
I recently bought a Seagate Goflex 3TB drive for $119 at Costco. Paid no tax because I got it on our states Tax free day. I bought this drive be cause I can later buy an adaptor that will make it a Thunderbird drive ( I have an iMac). My advice is get the most storage you can for what you’re paying. Both WD and Seagate make decent drives.
