Maybe I wasn't clear enough.

I've got data on a DVD disk - or rather: A number of them. I've got an analysis program reading the data on the disks, but it will read from a physical disk only. It will not read from a disk file, neither on flash nor magnetic disks.

I do not produce the data; I receive and analyze them. It is more or less a one-time operation. Even if I could make an ISO file before I start the analysis, as soon as the analysis is done, I would delete the ISO file; I would not retain it, neither on a magnetic or flash disk.

RAM access is a lot faster than even flash disks, even with the OS caching disk blocks accessed. But more important: Creating an ISO image file on a flash or magnetic disk as a precursor to the analysis takes time. Especially if the driver would let you start working immediately after the DVD disk has been inserted, essentially reading the data sequentially in the most efficient way but if you refer to data not yet read in would put the sequential reading on hold to serve your request before continuing, the total time from start to completion could be a lot less.

Those alternatives in the article you link to will do half the job: Putting data in RAM. But the other half is having it appear not as an NTFS or FAT disk, but as a physical device that can be read as a raw DVD disk, below the file system layer. None of the 12 alternatives claim to mimic a physical DVD interface, and will not be accessible to an analysis program that reads from such interfaces only.
