Arcserve 15 Disaster Recovery Disk

Am in the process of carrying out disaster recovery disks for our servers. Theres several options in Arcserve to produce this. Traditionally, we used to make a 'machine specific' disk and made a floppy disk with the DR info on. This was then inserted during 'ASR' mode (press F2 isnt it?) and the machine recovered from there.

However, theres now new options available:

Are there any major benefits of choosing on of the others? Apart from the reliability and speed of CD/DVD being better than FDD?

Cheers
