Music:
2.46 TB
93,987 songs
Your average song is 27MB each, what format is it in?
It would have to be lossless to take up 2.46TB with just 93k songs.
15TB of Movies/TV how many HD, how many SD approximately, to the nearest 10,000
9,000 TV SD episodes is about 4TB in H.264
1,000 DVD SD Movies at 3.5MBs 2 pass HB rip, don't really get much benefit going higher than that and you run other risks for playback, is about 2TB
So at that rate 15TB would be 7,500 SD DVD rips which would have taken two newish iMacs, with at least 4 external DVD ROMs attached each (so you could keep the rip going throughout the night, reloading them all three times a day), about a year flat out 24x7.
A massive accomplishment.
It has taken me a year to get a poultry 9,000 TV shows done, and I am now 250 DVDs into a 2,000 DVD collection and I and my two iMacs are pretty drained by the effort of the Big Rip.
Mine is complicated because I am capturing all the DVD extras and sound tracks/subtitles etc I don't want ever want to do this again!
