>21K individual titles or total CDs (that is, there may be >duplicates)? At a rate of 5 per hour, 8 hours per day, 7 days a >week, it would take you a year and a half to rip that many disks. I think not. While I did start ripping my CDs a year or so ago, the length of time is all about the speed of the processor. I found great pleasure with the purchase of newer computers and seeing my ripping time decrease dramatically. I currently have around 24,000 songs ripped and it takes up about 90 GB. As for the length of time, I don't know but do note that I've ripped my collection twice cuz I wanted to do it at a different rate as times have changed.
