I would think that SSD Advances would be part of this too. 2TB is commercially available in a 2.5" form factor If you had a purpose built 4U storage module with SSD Tech, wouldn't it be 100's of TB with almost no power draw?

I read an analysis recently (unfortunately I don't remember where it 
was) discussing the optimum size for a storage device. It was making 
the argument that the size itself becomes a problem when it exceeds 
16TB or thereabouts. When it gets much larger, it interferes with just 
getting data on/off because of transfer speeds and the shear amount of 
data contained therein (or thereon?).

It doesn't take into account the capacity of new drives increasing 
either though, so it could very well be close to linear, as far as 
physical space goes.

    That does not take into account the rate of growth. It's probably

    In one small corner of the larger data centers.  Those things
    are huge.  3000 square feed (including aisle space) against 10
    acre data centers.  Each data center would be good for 14 years
    and there are hundreds of data centers.

    I look at it a different way. First, they are probably using
    16TB drives (although I don't know). Based on what I've read,
    16TB is the sweet spot for efficient large storage. That said, a
    single rack a day seems like a big deal to me. That's 365 racks
    per year. Yeesh. Talk about real estate. They are probably
    having to get creative on where to park all that stuff.
    Oh yeah. Monetization too.
