Falcon SCSI tops at around 2MB/s. 1X CD = 176400 bytes/s. At 8X the SCSI would not manage if you both read and write from/to it. At 6X you would be pushing it and likely get underruns at times.

The solution is to read from IDE (a modern one! the old ones from when the Falcon was made are hoplessly slow) and write to SCSI. Then, theoreticly you should be able to reach 11X speed. But in reality perhaps 8X would be fine.

USB 1.1 is 12Mbit/s, equals theoretical maxium of 1.46MB/s, which is pretty much 8X CD speed.

As you see, it's not much of the CPU power that matters, it's the disk I/O around it.
