I just finished importing 403 cd's in the last 4 days, about 100 cds a day and the fastest it imported was about 5mins. I think it depends on the year the disc was made and / or quality of both the disc and the chosen bit-rate. Only about 4-5 discs out of the 403 froze and kept spinning leaving me to force quit, not bad at all. I'd rather it be a bit slower than getting those anoying glitches and clicks in the audio.
