What writer is it...if it is a liteon 32x I would say based on my 24x liteon it will take about 4-5 min to read a safedisc title and about 3 min 30 sec to write on a 32x..those are ballpark figures....

now when you read with clonecd you may get a crazy read time of hours but once you get passed the errors on the disc (ie after sector 10,000) it will fly..some readers will read errors faster than others...

hope this helps
