I've recently started reading up on RAM disks, and they really do sound like they could boost a computer's speed. However, I was wondering if there was a way to go even further and make a RAM disk one of the volumes in a DIY Fusion Drive. Is there a way, keeping in mind the fact that RAM loses its data upon losing power, to safely make a DIY Fusion Drive featuring a RAM disk?
Fusion Drive acts as an extension to the installed HD, it is not a cache. If you would use a RAM disk as the SSD part for your DIY Fusion Drive you would loose the data stored in the RAM part whenever the system shuts down.
