What on earth are you doing with a 71 TB personal filesystem?

It is amazing once you start working with video how much space you can use with RAW formats and all the files you create. A Red EPIC in HDRx at 8:1 at 5K is almost 6GB/minute.

  What amazes me is that not long ago this was Hollywood class specs. http://en.wikipedia.org/wiki/Monsters_vs._Aliens http://en.wikipedia.org/wiki/Monsters_vs._Aliens required 120TB of data.

    RED is Hollywood-class, though towards the lower end. A lot of big-name movies that you've heard of include scenes shot on RED cameras: http://www.red.com/shot-on-red http://www.red.com/shot-on-red. The TV show Leverage was shot entirely on a pair of RED Xs. RED's stuff is on the order of $25k. The main player for digital cinema is Arri ALEXA, on the order of $50k. It's not that far off.

      Yeah I've read big names switching to RED (that's what made their business thrive). I was also referring to the disk space. A single person can assemble a 100TB setup. That was Pixar territory not long ago.

    The amount of space isn't so impressive, but the physical size and number of spindles. I worked at one place that had 3 100tb disk arrays, each one was spread over 15 racks, giving 3gig a second throughput. (in 2007) Now, 170 tbs, and a server fit in 5u. 60 disks give 2gigs(bytes) a second throughput. 2.5 racks gives you 5.5PBs and ~60gigabytes/second peak (25-8 sustained)

I have about 27TB raw in my home, one btrfs and one zfs. The btrfs one is now primary, which is 'only' about 6TB usable, given 4x redundancy. We take a lot of high-def video, which is 1GB/minute, compressed out of the camera. So 16 hours takes about 1TB.

...or more than 640K of memory? Seriously, it's easy to amass significant amounts of data from 720p or 1080p video, 20+ MP camera shooting in RAW, and whatnot. And that's before you rip your DVD collection so the kids can watch movies without scratching up the disks.
