I thought waking up at 3am, shambling to my desk and connecting to the VPN was bad. Imagine having to drive down to the datacenter and rack 200 hard drives.
Sweet, I appreciate that info :) I imagine 5PB fills up quite quickly for Google too!
At that scale, it's just a function of (number of ethernet cables) x (avg size of ethernet cables), rather than disk space in their data center, I'd imagine!
And I remember reading a tweet from a Google engineer that they would be paged if their free storage dropped below 5PB.
