Yes, but the idea is obviously to use the RAM disk only for temporary files and to make everything recoverable in case of a crash. For example, if the TM is on the RAM disk but the file that you're translating is a bilingual file that is saved on the SSD/HDD, then your segments' translations are always recoverable.

It is my understanding that OmegaT does not read or write to the disk when doing things like matching and searching TMs, but instead performs most things in memory. This is why, when you start OmegaT, you can change a setting in the config file to increase the amount of RAM used by OmegaT (default is 1 GB). Searching external files is something that OmegaT does do directly from the disk, but OmegaT's external file search is so bad that you should never use it anyway.

An SSD is still much, much slower than a RAM disk. My computer's RAM is 10-20 times faster than my fastest SSD.
