Currently in my machine is ~22.75TB of porn, though I'm confident I have another drive or two with more I just need to find the time to swap some drives to verify.
I'm slowly going through it all and deleting fluff/filler content(the majority of my storage is JFF/OF content rips) from pages leaving only stuff worth watching, i.e., has some kind of pay-off.
Anything not deleted will get queued up for batch jobs I do here and there running entire folders through Handbrake for HEVC/x265 encoding.
