on what you consider to be "my" media.
If "my" media is the stuff that I legally own, then 100%. If it's stuff that I own both legally and illegally, then also 100%.
If, however, you're talking about media that I consume, then then answer is in the 0-20% bracket. Almost everything I watch comes from Netflix. Music I play comes from streaming radio. Even the log fireplace with xmas carols is a 3-hour-long Youtube video.
I would consider this media to be "stored" because it remains available to me, and I can go back and consume it again with less effort than putting one of my DVDs on to play. This is in comparison to cable or OTA transmissions, which are ephemeral and cannot be watched again, unless they are recorded somehow.
Of course, I could be ultra-pedantic (who doesn't like pedants?) and say 100%. Even the stuff that is not stored locally on non-volatile storage media is at least loaded into RAM before it's displayed/output. And technically, that's short-term local storage.
