I got an email today reminding me about the changes to Google Photos,
and how they're going to be counting against your Drive storage limit.
The email said that "4.3 million GB of data are uploaded to
drive/photos/docs every day"
4,300,000 GB = 4199 TB = 4.1 PB
So some quick back of the napkin math
4.1PB, Rumors are that Google creates 3 copies of all data for
redundancy. So every day they have to provide new storage for ~12.3PB
of storage
Take an average size Hard drive of ~12TB That's 1050 hard Disks per day.
For math's sake, a backblaze storage pod can hold 60 disks in 4U. So
that's 18 Drive pods per day. So 72U of rackspace. That's only a
single rack per day, Not bad. Data centers are big.
If they're getting the drives for $100 each, then that's $105,000/day or
$38.3M/year. So providing the storage for all of Google
photos/drive/docs is basically a rounding error to Alphabet.
Why are they having to limit my storage again?
I'm really curious how much raw data is uploaded to youtube every day,
but I haven't seen any publicly available figures recently (within the
last several years).
