Are You Traveling Forward In Time?
Dude! Why would you want to store video on a small device? If you want to go "All Apple" then get a Time Capsule and drop all your large files on that or plug in a USB hard drive to an Airport Base Station. If you don't care, then just get a cheap WiFi router and USB HDD.
If you want them so that you can have them on the road, then you can buy one of those WiFi HDDs from Seagate (I still don't trust Seagate) or if you are savvy, set up VNC and remotely access your home drives. That's how us people from 2012 do it.
