I want to grab one of these, and have found these three. I don't really care too much about online access or streaming to loads of devices (I don't have a TV or tablet or anything fancy). I essentially just want to transfer my files once (maybe 2tb worth), do some periodic syncing (I might even just do that manually), and access movies and music from it on my PC. Gonna grab a 6tb, as 3tb is probably enough for a good while. Amazon reviews are fairly helpful, but it sounds like just about all these deviceshave problems of slow transfers for at least some people. I've been looking at these three. Anyone know if these are any good?

I have a WD My Book 3TB hooked to my router, it's been great. Leave it on 24/7, it's been running non-stop since I got it in March of 2013.
