A: Two factors determine how quickly the import will be done: changer data extraction rate and CPU audio file conversion rate. The overall disc import speed will be the lower of these two rates.
The PowerFile R200 MFX changer is capable of extracting data from Audio CD's at a speed of about 13-14 discs/hour. If you connect two changers, this number will be doubled.
A PowerMac G5 dual 2.0GHz is capable of converting approximately 23-25 discs per hour to MP3 or AAC file format (this rate is much higher for AIFF or WAV files, since no compression is required).
Therefore, connecting one changer to a PowerMac G5 will result in an import rate of approximately 13-14 discs/hour (limited by the speed of the changer). Connect two changers and the import rate will increase to 23-25 discs/hour (limited by the speed of the PowerMac's CPU). Connecting a third changer will not increase the import rate, but will allow more discs to be imported in one job.
Examples of approximate times required for importing 96 discs with various changer configurations:
| 96 discs in 1 changer | 7 hours |
| 96 discs in 2 changers (48 in each) | 4 hours |
| 96 discs in 3 changers (32 in each) | 4 hours |
(examples are using PowerMac G5 dual-2.0GHz and PowerFile R200 MFX changers)
