Ok, I was having an urgent issue with my faithful Windows Home Media Server becoming cranky. I needed something to back up to quick. Being that I take a LOT of pictures, I needed something large. Luckily my local electronics shop had a 4TB Seagate Backup Plus for about $170 on hand. 4 TB, 2 year warranty, USB 3.0 and about $40 more than a comparable 3 TB-- what's not to like? So I grabbed it, brought it home, ripped open the box and proceeded to save my digital @**. I liked it enough that I thought it deserved digging into a bit deeper.
