Hi Dark_Jedi, Have you considered a WD My Cloud Mirror? It's definitely more expensive, but the benefit is that every file is automatically copied to two drives (via a mirrored RAID). If one drive ever fails, you can recover all of your data from the second drive. The backups all happen automatically and it will give you email warnings in advance if a failure is likely. It's also a DLNA media server.

Beyond the cost, the other issue is that if you do use it in mirrored RAID mode, a 4TB setup becomes only 2TB of usable data. For me, the extra peace of mind was worth the trade offs , but it's definitely something to consider. I like mine a lot.

I hope your son is feeling better. :)
