I've lost count, but upwards of 10,000 Movies/Shows (and ofc each show could have 10, 20 or even 100+ individual files) that only comes to about 100-120TBs
The remaining 150 or so (My usage is 280TBs, I just locked in a limit of 300) is, well, my entire life that isn't deemed so important as to go to my actual personal GDrive. It's not just some images, it has every image of every drive and device I've ever owned just prior to it being put out of service.
