The biggest issue is lack of UDMA, which is a killer. You may find that doing anything at all at the same time as burning will result in an expensive coaster. At best, you can expect huge burn times.

I still have memories of it taking over forty minutes to burn a CD on my Amiga/040 with standard IDE, and the computer was virtually frozen all through. It takes less than five on my PC or Pegasos, and everything is accessible. Wouldn't want to try burning a DVD on Amiga, except with SCSI or some form of IDE upgrade...


On my unexpanded Amiga4000/68040/25MHz/16MB FastRAM burning of 700MB CD on the Fly (not from ISO) takes 23 minutes and the Hard Disk is 5400 RPM, but I am using SFS. For burning DVDs with 4x you need 5,540 KB/second and at 2.4 x 3,324KB/s so this is not impossible speed for classic Amigas. The new writing devices (CD and DVDs) have the ability to wait and/or switch at slower writing speeds if the computer can't feed the data all the time - they are not like the old drives where if the buffer gets empty - the burning is canceled and the media is damaged. I think it's called Buffer Underrun Protection.
