Recently, I read an article about spinning disks that should scale
to 80 TB per 3.5" drive.

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.

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.

Monitization. One of the
first and richest of the non-founding googlers was
the director of
monitization...
