I'm waiting for the Nyko Databank to release (should be soon) so that I can get a 3.5" drive for my PS4.

At which point, I'll probably either go for a 6tb HDD, or 4tb SSHD (I'm not really sure what the benefits are, I guess they're faster, but I dunno if the ps4 supports those speeds / if they'd be noticeable).

If and when I eventually get an Xbox One (maybe sometime next year), hopefully by that point there'll be a 1tb+ SKU available. As I'd only be using it for exclusives, I don't see myself getting more than 10-20 games for it throughout its lifetime.

I use my Xbone for TV mostly and voice commanding all my entertainment, along with smartglass for an all-in-one remote. I also have an 8 way HDMI splitter. That little thing to the left of my PS4. I have it split to 3 TVs. One in the Family room, one in the living room and one in the place I spend most, the kitchen. So I can just smartglass from anywhere.

I've grown lazy of home console gaming. It's gotten too time consuming. I game mostly on my Vita these days. But when I eventually get tired of life and decide to just stay home all day, I'll have everything ready and waiting for me.

I will be getting a 5TB for mine.

To be honest, I don't play games all that much at the moment. Not through lack of want, just don't have the time these days. I actually do the same thing, just a bit of Vita action whenever I can slide in 10-15 minutes of game time here or there.

I don't watch TV, either. Also because of lack of time, but generally because I don't watch TV at all anyways. Sucks, 'cause I signed up to a 2 year cable contract last September, must have watched about 30 minutes of TV on it. /lesigh.

I will one day get myself a really awesome entertainment setup. Even if I never use it, it'll be one of those boyhood dreams that I will achieve.

Xbone actually runs pretty cool. It's in an open space and the vents with hot air on the right side. Don't think it'll be a problem.

I have a seagate oen liek OP has but a 3tb version and they are 7200rpm

same here as i zero space on teh ps4 atm lol.  I probably will go for 4tb  when nyko comes out. SSHD boots things faster then normal HDD .  Once you had the bone , you never want to go back :P

I haven't been gaming on my PS4 much at all so far. I've also got a 1TB exHDD laying around doing nothing for over a year now that I can dismantle and pop-in if needed.

I could do with that! Already had to remove several games because it was full.

As someone with a 2TB drive in my PS4 downloading everything I can trying to fill it up and still having 1.77 TB left, good luck. That 5 gigs will last you until the Xbox 3.
