With a nearly empty 2 GB ram disk, it takes 4 minutes for DataRamDisk to save an image of the ram disk.
It takes 2 minutes for DataRamDisk to save an image of an empty 1GB ram disk.
I'm pretty sure that their software won't let me separate the load and save functions, it's both or it's none.
I uninstalled the software after the ram disk didn't appear after one boot.
Too much grief for too little performance.
