You can use any of those for SAIT. The 8mm,8mm2, and 8mm3 are simply logical ways to seperate 8mm or AIT media if you have more than one drive type. If you don't than you can use any of them.
Hi, Whats the compression size for each of 8MM, 8MM2 and 8MM3?
If I have to backup for a given compression size, I need to know the compression size for each of these tape types, so that I can optimally use the tapes.
